media: cpia2: Fix a couple off by one bugs

2018-03-22T08:23:29+00:00

[ Upstream commit d5ac225c7d64c9c3ef821239edc035634e594ec9 ]

The cam->buffers[] array has cam->num_frames elements so the > needs to
be changed to >= to avoid going beyond the end of the array.  The
->buffers[] array is allocated in cpia2_allocate_buffers() if you want
to confirm.

hdpvr: hide unused variable

2018-02-25T10:03:49+00:00

commit b97baa3e22e18dac42001e665cf27ad1211bf878 upstream.

The i2c client pointer is only used when CONFIG_I2C is set, and
otherwise produces a compile-time warning:

drivers/media/usb/hdpvr/hdpvr-core.c: In function 'hdpvr_probe':
drivers/media/usb/hdpvr/hdpvr-core.c:276:21: error: unused variable 'client' [-Werror=unused-variable]

This uses the same #ifdef to hide the variable when the code using
it is hidden.

em28xx: only use mt9v011 if camera support is enabled

2018-02-25T10:03:49+00:00

commit 190b23b4eb997767afad186bd8c96badceabf39e upstream.

In randconfig builds that select VIDEO_EM28XX_V4L2 and
MEDIA_SUBDRV_AUTOSELECT, but not MEDIA_CAMERA_SUPPORT, we get
a Kconfig warning:

 warning: (VIDEO_EM28XX_V4L2) selects VIDEO_MT9V011 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT)

This avoids the warning by making that 'select' conditional on
MEDIA_CAMERA_SUPPORT. Alternatively we could mark EM28XX as
'depends on MEDIA_CAMERA_SUPPORT', but it does not seem to
have any real dependency on that itself.

go7007: add MEDIA_CAMERA_SUPPORT dependency

2018-02-25T10:03:49+00:00

commit fa6317eedd6341f2144ed1097706d8c34f18b6e4 upstream.

If MEDIA_SUBDRV_AUTOSELECT and VIDEO_GO7007 are both set, we
automatically select VIDEO_OV7640, but that depends on MEDIA_CAMERA_SUPPORT,
so we get a Kconfig warning if that is disabled:

warning: (VIDEO_GO7007) selects VIDEO_OV7640 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT)

This adds another dependency so we don't accidentally select
it when it is unavailable.

pwc: hide unused label

2018-02-25T10:03:45+00:00

commit 1f6bcd011464cb36059e2562f72baf75f98b732d upstream.

The pwc driver causes a warning when CONFIG_USB_PWC_INPUT_EVDEV is unset:

drivers/media/usb/pwc/pwc-if.c: In function 'usb_pwc_probe':
drivers/media/usb/pwc/pwc-if.c:1115:1: warning: label 'err_video_unreg' defined but not used [-Wunused-label]

This moves the unused label and code inside another #ifdef to
get rid of the warning.

media: cxusb, dib0700: ignore XC2028_I2C_FLUSH

2018-02-16T19:09:45+00:00

commit 9893b905e743ded332575ca04486bd586c0772f7 upstream.

The XC2028_I2C_FLUSH only needs to be implemented on a few
devices. Others can safely ignore it.

That prevents filling the dmesg with lots of messages like:

	dib0700: stk7700ph_xc3028_callback: unknown command 2, arg 0

media: dvb-usb-v2: lmedm04: move ts2020 attach to dm04_lme2510_tuner

commit 7bf7a7116ed313c601307f7e585419369926ab05 upstream.

When the tuner was split from m88rs2000 the attach function is in wrong
place.

Move to dm04_lme2510_tuner to trap errors on failure and removing
a call to lme_coldreset.

Prevents driver starting up without any tuner connected.
