From: Markus Elfring Date: Sun, 6 Nov 2016 19:40:20 +0000 (-0200) Subject: [media] DaVinci-VPBE: Check return value of a setup_if_config() call in vpbe_set_output() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2eaa68f33b86bf9a6c6cbfaf773d74f1f8bddd4e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] DaVinci-VPBE: Check return value of a setup_if_config() call in vpbe_set_output() * A function was called over the pointer "setup_if_config" in the data structure "venc_platform_data". But the return value was not used so far. Thus assign it to the local variable "ret" which will be checked with the next statement. Fixes: 9a7f95ad1c946efdd7a7a72df27db738260a0fd8 ("[media] davinci vpbe: add dm365 VPBE display driver changes") * Pass a value to this function call without storing it in an intermediate variable before. * Delete the local variable "if_params" which became unnecessary with this refactoring.
