Subject: [PATCH] [media] cxusb: increase buffer length to 80 bytes
As reported by Vincent:
[ 16.332247] xc2028 0-0061: Loading firmware for type=BASE F8MHZ (3), id 0000000000000000.
[ 16.344378] cxusb: i2c wr: len=64 is too big!
64 bytes is too short for firmware load on this device. So, increase it
to 80 bytes.
Bugzilla: 1154454
Upstream-status: 3.17
