You have sent him a patch that has triggered this response. He used to manually respond to these common problems, but in order to save his sanity (he kept writing the same thing over and over, yet to different people), I was created. Hopefully you will not take offence and will fix the problem in your patch and resubmit it so that it can be accepted into the Linux kernel tree. You are receiving this message because of the following common error(s) as indicated below: - Your patch contains warnings and/or errors noticed by the scripts/checkpatch.pl tool. If you wish to discuss this problem further, or you have questions about how to resolve this issue, please feel free to respond to this email and Greg will reply once he has dug out from the pending patches received from other developers. thanks, greg k-h's patch email bot ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
[PATCH v1] pinctrl: ralink: rt2880: Check for return value of devm_kcalloc()
The memory allocation function devm_kcalloc() may return NULL pointer, so it is better to add a check for 'p->func[i]->pins' to avoid possible NULL pointer dereference.
