First set of IIO fixes for the 5.13 cycle 

A couple of high priority core fixes and the usual bits scattered
 across individual drivers.
 
 core:
 * Fix ioctl handler double free.
 * Fix an accidental ABI change wrt to error codes when an IOCTL is not
   supported.
 
 gp2ap002:
 * Runtime pm imbalance on error.
 hid-sensors:
 * Fix a Kconfig dependency issue in a particularly crazy config.
 mpu3050:
 * Fix wrong temperature calculation due to a type needing to be signed.
 pulsedlight:
 * Runtime pm imbalance on error.
 tsl2583
 * Fix a potential division by zero.

Say yes here to build trigger support for HID sensors.
Triggers will be send if all requested attributes were read.
