Reported by checkpatch:
CHECK: Macro argument 'gcam' may be better as '(gcam)' to avoid precedence issues
Inline standard calls to 'dev_*' kernel logging functions, in favor of 'gcam_*' macros, to clear up gcam-related logging.

This looks good, thanks for doing this.
Nit: for the future, on a few of the dev_err() calls, the new first argument makes the line even wider than before. Lines wider than 80 columns are acceptable--especially when they contain formatted output--but you could have put the format string on a new line in a few of the cases. I'm old-skool and prefer making things fit in 80 columns unless it gets too ugly.

Changes in v2:
- Inline 'dev_*' logging functions, over wrappers and macros to just use the standard call.
- Remove 'gcam_*' macros, since they are no longer used.
