iio: st_pressure: st_accel: Initialise sensor platform data properly
[ Upstream commit 7383d44b84c94aaca4bf695a6bd8a69f2295ef1a ]
This patch fixes the sensor platform data initialisation for st_pressure
and st_accel device drivers. Without this patch, the driver fails to
register the sensors when the user removes and re-loads the driver.
1. Unload the kernel modules for st_pressure
$ sudo rmmod st_pressure_i2c
$ sudo rmmod st_pressure
2. Re-load the driver
$ sudo insmod st_pressure
$ sudo insmod st_pressure_i2c
