[PATCH] [SCSI] pm8001 missing break statements

Mark Salyzyn
2011-09-26T14:58:28Z

[-- Attachment #1: Type: text/plain, Size: 13564 bytes --]

Code Inspection: found two missing break directives. First one will
result in not retrying an a task that report
IO_OPEN_CNX_ERROR_HW_RESOURCE_BUSY, the second will result in cosmetic
debug printk conflicting statement stutter. Because checkpatch.pl came
up with a warning regarding unnecessary space before a newline on one of
the fragments associated with the diff context, I took the liberty of
fixing all the cases of this issue in the pair of files touched by this
defect. These cosmetic changes hide the break changes :-(

To help focus, break changes are in pm8001_hwi.c fragment line 1649 for
the IO_OPEN_CNX_ERROR_HW_RESOURCE_BUSY case statement and pm8001_sas.c
line 1000 deals with the conflicting debug print stutter.

The real patch is enclosed as an attachment since Outlook is my current
MTA. This code change has not shown any side effect in roughly a year of
random acts of testing.
