From: Markus Elfring Date: Sat, 3 Jun 2017 17:09:07 +0000 (+0200) Subject: ARM: OMAP2+: Use kcalloc() in sr_set_nvalues() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b72de4d331f058dbd8fa327f1e5d0a729583f56;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ARM: OMAP2+: Use kcalloc() in sr_set_nvalues() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
