Subject: [PATCH v3 27/41] iio: imu: inv_icm42600: make use of regmap_clear_bits(), regmap_set_bits()
 
This Message Is From an External Sender
This message came from outside your organization.
 
Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().
