2024-01-23iio: magnetometer: bmc150: Drop ACPI_PTR() usageJonathan Cameron1-2/+1
Avoiding unused variable warnings when using this macro adds complexity that in simple cases like this one is not justified for the small saving in data. Drop unused linux/acpi.h includes.

2022-02-18iio:magnetometer:bmc150: Move exports to IIO_BMC150_MAGN namespaceJonathan Cameron1-0/+1
In order to avoid unnecessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the bus specific device drivers that use them. Note the MAGN postfix here is reflecting that this driver is only responsible for part of the BMC150 device.

2022-02-09spi: make remove callback a void functionUwe Kleine-König1-3/+1
The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2020-04-19iio: magn: bmc150: Use vsprintf extension %pe for symbolic error nameNishant Malpani1-2/+2
Utilize %pe format specifier from vsprintf while printing error logs with dev_err(). Discards the use of unnecessary explicit casting and prints symbolic error name which might prove to be convenient during debugging.
