Subject: fbdev: propagate result of fb_videomode_from_videomode()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9f5ddefdc979d7b71aa4d3d7cc456c76fee80fda;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

fbdev: propagate result of fb_videomode_from_videomode()

fb_videomode_from_videomode() may fail, but of_get_fb_videomode()
silently covers this fact. Instead, trow the error code to the
caller.
