Subject: drivers/video/fbmem.c: simplify strlen()==0 check in fb_get_options()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a67ef278e24b1fe5ab8f5e8ef27f9654b91732de;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drivers/video/fbmem.c: simplify strlen()==0 check in fb_get_options()

Replaced !strlen(str) check with !str[0].  Removed the variable which was
used solely to store strlen result.
