Subject: V4L/DVB (7608): em28xx-dvb: Some cleanups and fixes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83244025e70aadd7e8baad520decf5d53d534d8f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

V4L/DVB (7608): em28xx-dvb: Some cleanups and fixes

em28xx-dvb.c:
 - Remove unneeded xc3028_ctrl structure.  The driver automatically preserves
   the previous value

tuner-xc2028.c:
 - Make the return type for xc2028_get_reg signed, since all of the callers
   are looking for "< 0" to detect errors.
