2014-11-05staging:iio:ade7758: Fix check if channels are enabled in prenableLars-Peter Clausen
We should check if a channel is enabled, not if no channels are enabled.

2014-11-05staging:iio:ade7758: Fix NULL pointer deref when enabling bufferLars-Peter Clausen
In older versions of the IIO framework it was possible to pass a completely different set of channels to iio_buffer_register() as the one that is assigned to the IIO device. Commit 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.") introduced a restriction that requires that the set of channels that is passed to iio_buffer_register() is a subset of the channels assigned to the IIO device as the IIO core will use the list of channels that is assigned to the device to lookup a channel by scan index in iio_compute_scan_bytes(). If it can not find the channel the function will crash. This patch fixes the issue by making sure that the same set of channels is assigned to the IIO device and passed to iio_buffer_register(). Note that we need to remove the IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE info attributes from the channels since we don't actually want those to be registered.

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

2014-11-05mmc: core: fix card detection regressionKristina Martsenko
Since commit 89168b489915 ("mmc: core: restore detect line inversion semantics"), the SD card on i.MX28 (and possibly other) devices isn't detected and booting stops at: [ 4.120617] Waiting for root device /dev/mmcblk0p3... This is caused by the MMC_CAP2_CD_ACTIVE_HIGH flag being set incorrectly when the host controller doesn't use a GPIO for card detection (but instead uses a dedicated pin). In this case mmc_gpiod_request_cd() will return before assigning to the gpio_invert variable, leaving the variable uninitialized. The variable then gets used to set the flag. This patch fixes the issue by making sure gpio_invert is set to false when a GPIO isn't used. After this patch, i.MX28 boots fine. The MMC_CAP2_RO_ACTIVE_HIGH (write protect) flag is also set incorrectly for the exact same reason (it uses the same uninitialized variable), so this patch fixes that too.

2014-11-04[media] media/rc: Send sync space information on the lirc deviceAustin Lund
Userspace expects to see a long space before the first pulse is sent on the lirc device. Currently, if a long time has passed and a new packet is started, the lirc codec just returns and doesn't send anything. This makes lircd ignore many perfectly valid signals unless they are sent in quick sucession. When a reset event is delivered, we cannot know anything about the duration of the space. But it should be safe to assume it has been a long time and we just set the duration to maximum.

2014-11-04[media] af9033: fix AF9033 DVBv3 signal strength measurementAntti Palosaari
Previous patch changes used signal strength firmware register from 0x800048 to 0x80004a in case of AF9033/AF9035 chip. In practice reported values were running upside-down, when RR strength increases reported value decreases and vice versa. That is because of 0x80004a returns values that are dBm scale, but negative RF strength dBm returned as positive number. 0x800048 returns 0-100, like percentage 0x80004a returns 0-255 dBm, without a negative sign So restore old measurement now.
