[PATCH v3 2/2] iio: hid-sensors: Use implicit NULL pointer checks

[Sanjay Chitroda via B4 Relay]

From: Sanjay Chitroda <sanjayembeddedse@xxxxxxxxx>

Replace explicit NULL pointer comparisons with implicit checks across
HID sensor IIO drivers to fix kernel coding style.

CHECK: Comparison to NULL could be written ...

No functional change.
