From: Markus Elfring Date: Tue, 25 Apr 2017 09:20:41 +0000 (+0200) Subject: HSI: omap_ssi: Use devm_kcalloc() in ssi_add_controller() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4a8557de7fb0be63e4e783ad4ad77463afb0d611;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git HSI: omap_ssi: Use devm_kcalloc() in ssi_add_controller() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "devm_kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
