The comment for start_streaming that tells the developer with which vb2 state buffers should be returned to vb2 gave the wrong state. Very confusing. Signed-off-by:

Recently WARN_ON() calls have been added to warn if the driver is not properly returning buffers to vb2 in start_streaming (if it fails) or stop_streaming(). Add comments before those WARN_ON calls that refer to the videobuf2-core.h header that explains what drivers are supposed to do in these situations. That should help point developers in the right direction if they see these warnings. Signed-off-by:

IT9135 RF tuner clock is coming from demodulator. We need enable it early in demod init, before any tuner I/O. Currently it is enabled by tuner driver itself, but it is too late and performance will be reduced as some registers are not updated correctly. Clock is disabled automatically when demod is put onto sleep. Cc: <stable@vger.kernel.org> # v3.15+ Cc: Bimow Chen <Bimow.Chen@ite.com.tw> Signed-off-by:

We should not select SPI bus when sub-driver auto-select is selected. That option is meant for auto-selecting all possible ancillary drivers used for selected board driver. Ancillary drivers should define needed dependencies itself. I2C and I2C_MUX are still selected here for a reason described on commit 347f7a37 Reverts commit e4462ffcReported-by:

The sensor may be powered by either one of its sub-devices being accessed from the user space (an open file handle) or by its s_power() op being called with non-zero on argument. The driver counts the users and if any reason to keep the device powered exists it will be powered. However, a faulty condition was used in recognising the need to power off the sensor, leading it to be powered off every time any of its uses went away. Signed-off-by:

This driver adds support for the built-in accelereometer found on recent Toshiba laptops with HID TOS620A. This driver receives ACPI notify events 0x80 when the sensor detects a sudden move or a harsh vibration, as well as an ACPI notify event 0x81 whenever the movement or vibration has been stabilized. Also provides sysfs entries to get/set the desired protection level and reseting the HDD protection interface. Signed-off-by:

Azael Avalos authored
Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support. This patch changes the set_lcd_brightness function, checking the returned values for values greater than zero to avoid registering a broken backlight interface. Signed-off-by:
