X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24e7d7990179e5ed38e90d78d12c25fa201c618a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: cxt1e1: Removed assignments from if statements. Assignments removed from if statements. Fixed checkpatch warning such as indentation and negative error returns in adjacent code. Coccinelle was used for this patch.
