From: Fabio Estevam Date: Wed, 12 Aug 2015 17:39:38 +0000 (-0300) Subject: crypto: caam - Remove unneeded 'ret' variable X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e558017b558d2a477b68961b0da792d4346a01b4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git crypto: caam - Remove unneeded 'ret' variable Variable 'ret' is only used for returning the value 0. We can make it simpler and just return 0 instead. The semantic patch that makes this change is available in scripts/coccinelle/misc/returnvar.cocci.
