Subject: ASoC: Correct code taking the size of a pointer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc2580061e42c323d7777029f01318f395edac0d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ASoC: Correct code taking the size of a pointer

sizeof(codec->reg_cache) is just the size of the pointer.  Elsewhere in the
file, codec->reg_cache is used with sizeof(wm8900_reg_defaults), so the
code is changed to do the same here.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression *x;
expression f;
type T;
@@

*f(...,(T)x,...)
// </smpl>
