Subject: [PATCH v2] staging: media: atomisp: replace [pr|dev]_info() by
 dev_dbg()
Message-ID: <20210423172129.GA254325@localhost>
MIME-Version: 1.0

It is recommended to use driver model diagnostic macros dev_*() instead
of pr_*() since the former ensures that the log messages are always
associated with the corresponding device and driver. Also, using
dev_dbg() is less log spamming as against dev_info().

Changes in v2:
   - use dev_dbg() instead of dev_info(). Feedback from Hans Verkuil.
   - update patch summary and description accordingly.
