media: dvb-frontends/stv0910: deduplicate writes in enable_puncture_rate()
For all code rates, the same write is performed, only with a differing value. Clean this up by putting that value into a variable instead and perform the write at the end with that value. Picked up from the dddvb upstream. Cc: Ralph Metzler <rjkm@metzlerbros.de> Signed-off-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
