[media] drivers/media/dvb/ttpci/av7110_av.c: Add missing error handling code
Extend the error handling code with operations found in other nearby error handling code. A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {... S1 return -C1;} ... *if (...) {... when != S1 return -C2;} ... *if (...) {... S1 return -C3;} // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
