The proposed mechanism was to use reserved-memory and memremap() the region while it should be available in Linux, but while this would work for some cases (e.g. memory regions for semi-static firmware executed by co-processors) it doesn't handle the scenarios where the memory-need is dynamic. So suggestions are very welcome on how to better handle this.

[PATCH v2 2/4] staging: rtl8723bs: refactor rtw_macaddr_cfg()
Using is_broadcast_ether_addr() and is_zero_ether_addr() instead of testing each byte of the mac[] array for 0xff and 0x00 shortens the code and improves readability. If np == NULL, of_get_property() returns NULL, hence the "np" check is not needed. Instead of a fixed default mac address use a random one to reduce the likelihood of mac address collision. Thanks to Joe Perches and Dan Carpenter.

Re: [PATCH v3] staging: pi433: replace simple switch statements
If there are going to be actual users in the specific near term then that's fine.

Re: [PATCH v3] staging: pi433: replace simple switch statements
Hi Dan, I'd like to mention once more, that the idea of the abstraction was to support multiple modules of Hope-RF. If the decision of the "team" of developer of this driver is, that it should be reduced to a Pi433 or RFM69CW driver only, I fully agree, that the abstraction layer isn't necessary (tough improving readability). But if the "team" wants to extend the driver - here I explicitly want to Name Marcin Ciupak and Hogo Lefeuvre, both were discussing this with me - I highly recommend to keep the abstraction layer. And once again, I have to announce, that - if noone appears, who wants to help me with selling Pi433 - I can't effort to let Pi433 on the market longer then end of this year. From this Point of view on long term it might be senseless to prepare a Pi433-only driver.

[PATCH] staging: media: omap4iss: Added SPDX license identifiers
Added missing SPDX license identifiers to all files of the omap4iss driver. Most files already have license texts which clearly state them to be licensed under GPL 2.0 or later. SPDX identifiers were added accordingly. Some files do not have any license text. SPDX identifiers for GPL 2.0 were added to them, in accordance with the default license of the kernel.

Re: [PATCH v3] staging: pi433: replace simple switch statements
I'd still prefer if we just removed this abstraction entirely and used OPMODE_MODE_TRANSMIT everywhere instead of bringing "transmit" into it. I know that every author thinks their abstraction will definitely be useful in the future, but generally kernel style is to remove abstractions. But I guess this code is an improvement over the original so the patch is fine. regards, dan carpenter ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

Hadn't found the "--types=spacing" option. I'd fixed all the spacing issues in that file in a previous patch set. That space issue was in a commented out section of code, which is why I missed it previously. I think that file has all space issues cleared so there's only the single fix in this patch. ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
