[PATCH v3] staging: most: dim2: convert pr_info/err/warn to dev_info/err/warn

[PATCH v3] staging: most: dim2: convert pr_info/err/warn to dev_info/err/warn

[Zeeshan Ahmad]

The dim2 driver currently uses generic pr_* logging macros. Hardware
drivers should use the device-specific dev_* logging macros to provide
better context in the system logs, especially in systems with multiple
controller instances.

This patch converts all applicable logging calls in dim2.c to use the
proper device-specific APIs.

v3:
 - Removed "staging-next" and redundant "[PATCH]" from the subject line.
 - Shortened commit message lines to stay under 75 characters.
 - Added this changelog below the "---" as suggested by Ethan Tidmore.
 - Cleaned up temporary submission notes from the permanent commit body.
v2:
 - Rebased against the staging-next branch.
 - Fixed CC list to include relevant maintainers.

And note, that's the problem with going "too fast", you spent time
respinning patches without allowing others to review the original patch.
Please slow down and send updates maybe once a week.  There is no rush
here.
