[PATCH 15/16] media: i2c: max9286: Rework comments in .bound()

From: Jacopo Mondi
Date: Tue Feb 16 2021 - 12:46:37 EST


Re-phrase a comment in .bound() callback to make it clear we register
a subdev notifier and remove a redundant comment about disabling i2c
auto-ack.

No functional changes intended.
