* [media] mt2063: properly handle return error codesMauro Carvalho Chehab2012-10-06
| | | | | | | | | | | | | | | | | | | | | | | Fix a series of warnings when compiled with W=1: drivers/media/tuners/mt2063.c: In function 'mt2063_setreg': drivers/media/tuners/mt2063.c:290:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] ... drivers/media/tuners/mt2063.c:2013:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] drivers/media/tuners/mt2063.c:2271:14: warning: no previous prototype for 'tuner_MT2063_SoftwareShutdown' [-Wmissing-prototypes] drivers/media/tuners/mt2063.c:2286:14: warning: no previous prototype for 'tuner_MT2063_ClearPowerMaskBits' [-Wmissing-prototypes] Several of those warnings are real bugs: the error status code used to be unsigned, but they're assigned to negative error codes. Fix it by using unsigned int. While here, comment the two power management functions, while we don't add a code there to properly handle tuner suspend/resume.

* [media] drivers/media/tuners/mt2063.c: Removes useless kfree()Peter Senna Tschudin2012-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove useless kfree() and clean up code related to the removal. The semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ position p1,p2; expression x; @@ if (x@p1 == NULL) { ... kfree@p2(x); ... return ...; } @unchanged exists@ position r.p1,r.p2; expression e <= r.x,x,e1; iterator I; statement S; @@ if (x@p1 == NULL) { ... when != I(x,...)

* [media] common: move media/common/tuners to media/tunersMauro Carvalho Chehab2012-08-13
Move the tuners one level up, as the "common" directory will be used by drivers that are shared between more than one driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
