From: Joe Perches <joe@perches.ccom>
Return early when logging level too low.
Use normal kernel codeing style for function braces.
Add const where appropriate to logging functions.
Remove now unused #define QL_DBG_BUF_LEN.

From: Chad Dupuis @ 2011-11-18 17:03 UTC (permalink / raw)
To: jbottomley; +Cc: giridhar.malavali, chad.dupuis, andrew.vasquez, linux-scsi
This patch contains minor fixes to our new logging infrastructure:
- Remove extranous messages.
- Re-add 'nexus' and 'hdl' information.
- Adjusted the message ids to fill up the holes.
- Display FCP_CMND priority on update.
- Log only mail box error conditions.
- Do not print "Firmware ready **** FAILED ****" if cable is unplugged.
- Drop noisy 'fw_state...curr time...' message.
- Correct nexus display during abort.
- Add a special case error-logging set to '1'.
- Catagorize I/O exception display handling.
- Correct the bsg msg code printing.
- Dont use dynamic logging after host is removed.

That should be (char *). (void *) is a pointer to an incomplete type
and as such pointer arithmetic on it is technically illegal. gcc treats
it as char * for this purpose, so the expression works, but other
compilers (or some future version of gcc) might not be so lenient.

The driver should ensure there's a sufficient number of IOCBs
to satisfy the number of scatter-gather entries specified in the
command. Add a 'count' to the control structure, srb_ctx, to use
in qla2x00_alloc_iocbs().

Some variables need to be initialized before we config PCI I/O config space
or else strange firmware initialization errors may occur.
