From: Jiri Pirko Date: Tue, 16 Feb 2016 14:14:48 +0000 (+0100) Subject: rocker: remove trans parameter to rocker_cmd_exec function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae3907ecedb91c10ab8fd8b42ef62431206eee83;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rocker: remove trans parameter to rocker_cmd_exec function The only purpose of passing this parameter is to check for prepare phase. The only reason for a failure in that state is if TLVs don't fit into descriptor. That is highly unlikely and if that happens, it is a driver bug. So remove this parameter from rocker_cmd_exec, and check for prepare phase in caller. Signed-off-by: Jiri Pirko Signed-off-by: David S.
