Subject: V4L/DVB (9499): cx88-mpeg: final fix for analogue only compilation + de-alloc fix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1a8dc86db1546f60a25f2b5cd071c0091db87146;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

V4L/DVB (9499): cx88-mpeg: final fix for analogue only compilation + de-alloc fix

Final fix for when analogue only is selected
for compilation (ie, !CX88_DVB)

This tidies up previous fix and adds missing
de-alloc memory leak on fault (eg, if fe1 fails to alloc
where fe0 was allocated).
