Returning an error value in an i2c remove callback results in a generic error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. So instead of triggering the generic i2c error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making i2c remove callbacks return void. Signed-off-by:

Remove unnecessary channel check from rzg2l_adc_read_label(), as the channel error handling is already done in probe(). Therefore no need to validate at runtime. Signed-off-by:

This driver doesn't need to access I/O ports directly via inb()/outb() and friends. This patch abstracts such access by calling ioport_map() to enable the use of more typical ioread8()/iowrite8() I/O memory accessor calls. Suggested-by:

When sensor location is known, populate iio sysfs "label" attribute: * "accel-base" : the sensor is in the base of the convertible (2-1) device. * "accel-display" : the sensor is in the lid/display plane of the device. * "accel-camera" : the sensor is in the swivel camera subassembly. The non-standard |location| attribute is removed, the field |loc| in cros_ec_sensors_core_state is removed. It apply to standalone accelerometer as well as IMU (accelerometer + gyroscope) and sensors where the location is known (light). Signed-off-by:

This is a conversion to device-managed by using devm_iio_device_register() inside probe function. Previously the bma400 was not put into power down mode in some error paths in probe where it now is, but that should cause no harm. The dev_set_drvdata() call, bma400_remove() function and hooks in the I2C and SPI driver struct is removed as devm_iio_device_register() function is used to automatically unregister on driver detach.

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
