Hi Dan, the above lines of code were not in the original except "goto init_cc_res_err;" which was doing the error handling at different places. This patch has added those first three lines.

Ideally, the goto name should say what the goto does. In this case it does everything. Unfortunately trying to do everything is very complicated so obviously the error handling is going to be full of bugs. The first thing the error handling does is: ssi_aead_free(new_drvdata); But this function assumes that if new_drvdata->aead_handle is non-NULL then that means we have called: INIT_LIST_HEAD(&aead_handle->aead_list); That assumption is false if the aead_handle->sram_workspace_addr allocation fails. It can't actually fail in the current code... So that's good, I suppose. Reviewing this code is really hard, because I have to jump back and forth through several functions in different files. Moving on two the second error handling function: ssi_hash_free(new_drvdata); This one has basically the same assumption that if ->hash_handle is allocated that means we called: INIT_LIST_HEAD(&hash_handle->hash_list); That assumption is not true if ssi_hash_init_sram_digest_consts(drvdata); fails. That function can fail in real life. Except the the error handling in ssi_hash_alloc() sets ->hash_handle to NULL. So the bug is just a leak and not a crashing bug. I've reviewed the first two lines of the error handling just to give a feel for how complicated "do everything" style error handling is to review. The better way to do error handling is: 1) Only free things which have been allocated. 2) The unwind code should mirror the wind up code. 3) Every allocation function should have a free function. 4) Label names should tell you what the goto does. 5) Use direct returns and literals where possible. 6) Generally it's better to keep the error path and the success path separate. 7) Do error handling as opposed to success handling. one = alloc(); if (!one) return -ENOMEM; if (foo) { two = alloc(); if (!two) { ret = -ENOMEM; goto free_one; } } three = alloc(); if (!three) { ret = -ENOMEM; goto free_two; } ... return 0; free_two: if (foo) free(two); free_one: free(one); return ret; This style of error handling is easier to review. You only need to remember the most recent thing that you have allocated. You can tell from the goto that it frees it so you don't have to scroll to the bottom of the function or jump to a different file. regards, dan carpenter ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

I verified the patch set on CrytoCell HW and it's fine. Unfortunately, my coding style fixes patch set made two of these to fail to apply. Following up is a rebased patch.

[PATCH 3/3] staging: ccree: Use platform_get_irq and devm_request_irq
From: Suniel Mahesh It is recommended to use managed function devm_request_irq(), which simplifies driver cleanup paths and driver code. This patch does the following: (a) replace platform_get_resource(), request_irq() and corresponding error handling with platform_get_irq() and devm_request_irq(). (b) remove struct resource pointer(res_irq) in struct ssi_drvdata as it seems redundant. (c) change type of member irq in struct ssi_drvdata from unsigned int to int, as return type of platform_get_irq is int and can be used in error handling. (d) remove irq_registered variable from driver probe as it seems redundant. (e) free_irq is not required any more, devm_request_irq() free's it on driver detach. (f) adjust log messages accordingly and remove any blank lines.

[PATCH 2/3] staging: ccree: Convert to devm_ioremap_resource for map, unmap
From: Suniel Mahesh It is recommended to use managed function devm_ioremap_resource(), which simplifies driver cleanup paths and driver code. This patch does the following: (a) replace request_mem_region(), ioremap() and corresponding error handling with devm_ioremap_resource(). (b) remove struct resource pointer(res_mem) in struct ssi_drvdata as it seems redundant, use struct resource pointer which is defined locally and adjust return value of platform_get_resource() accordingly.

[PATCH 0/4] staging: ccree: coding style clean ups
Misc. coding style fixes for ccree driver. These are the missing patches that failed to apply two weeks ago, rebased onto latest staging-next. By the way, I still do not understand why they failed to apply, as they applied just fine being cherry picked on top of latest staging-next apart for fixes for later changes. I hope these will be good.

Is there anything in the kernel log? There is a slight difference in this patch and the one that got pushed in android-4.9[1]. I cherry-picked those changes and got BT/WiFi working again on Hikey with mainline tracking (4.13-rc2) tree.

Re: [PATCH v2] staging: lustre: replace simple_strtoul with kstrtoint
I did test it and not everything works as expected. I need to reconsider that change. Please drop this patch. Thanks, Marcin P.S. Sorry for late (sic!) response.
