2015-04-08[media] media: radio-si4713: improve usage of gpiod APIUwe Kleine-König
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify accordingly. Moreover use the _optional variant which has tighter error checking, but is simpler to use which allows further simplification.

2015-04-02[media] wl128x-radio really depends on TI_STArnd Bergmann
All other drivers using the TI_ST infrastructure use 'depends on' for this symbol, and it makes no sense to only enable that if CONFIG_NET is enable, because the radio driver also depends on CONFIG_NET itself: ERROR: "skb_queue_purge" [drivers/media/radio/wl128x/fm_drv.ko] undefined! ERROR: "skb_push" [drivers/media/radio/wl128x/fm_drv.ko] undefined! ERROR: "skb_pull" [drivers/media/radio/wl128x/fm_drv.ko] undefined!

Commit 0ba2aeb6dab80920edd9cf5b93b1ea4d6913b8f3 increased the internal control ranges to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value control values in a division or modulus operations since not all architectures support those natively. Luckily, in almost all cases it is possible to just cast to 32 bits (the control value is known to be 32 bits, so it is safe to cast).

2014-07-17[media] v4l2-ctrls: use ptrs for all but the s32 typeHans Verkuil
Rather than having two unions for all types just keep 'val' and 'cur.val' and use the p_cur and p_new unions to access all others. The only reason for keeping 'val' and 'cur.val' is that it is used all over, so converting this as well would be a huge job.

2014-02-28[media] radio-cadet: avoid interruptible_sleep_on raceHans Verkuil
interruptible_sleep_on is racy and going away. This replaces one use in the radio-cadet driver with a wait_event_interruptible call. Special care was taken that accesses to the rdsin and rdsout indices are always done with dev->lock held.
