From: Markus Elfring Date: Tue, 11 Oct 2016 07:40:41 +0000 (-0300) Subject: [media] DaVinci-VPBE: Use kmalloc_array() in vpbe_initialize() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f42afd29e60585904fc5127862263437ed7cbbd5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [media] DaVinci-VPBE: Use kmalloc_array() in vpbe_initialize() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". 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.
