Subject: V4L/DVB (9623): tvaudio: Improve debug msg by printing something more human
X-Git-Tag: v2.6.28-rc5~7^2~1
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c6241b6c64dbe759e0eccaee913bdcf4d7960367;p=linux-2.6-omap-h63xx.git

V4L/DVB (9623): tvaudio: Improve debug msg by printing something more human

Before the patch, the used ioctl were printed as an hexadecimal code,
hard to be understand without consulting the way _IO macros work.
Instead, use the V4L default handler for printing such errors into a way
that would be easier to understand.
