From: Bart Van Assche @ 2015-01-27 9:33 UTC (permalink / raw)
To: Christoph Hellwig; +Cc: Quinn Tran, Saurav Kashyap, linux-scsi@vger.kernel.org
Replace the QLA82XX_ADDR_IN_RANGE() and QLA8044_ADDR_IN_RANGE() macros
with the inline function addr_in_range(). This avoids that the compiler
reports the following warning when building with W=1: comparison of
unsigned expression >= 0 is always true.

Whether htonl() or __constant_htonl() is used, if the argument
is a constant the conversion happens at compile time. Hence leave
out the __constant_ prefix for this and other endianness
conversion functions. This improves source code readability.

This patch removes 21 casts between an __iomem pointer type and
another data type but also introduces five new casts (see also
the casts with "__force"). Although this patch does not change
any functionality, IMHO the code with __force casts needs further
review.

The "return QLA_SUCCESS" statement just above the "fw_load_failed"
label cannot be reached, hence remove it. Additionally remove the
"else" keyword since the code block below the if-statement ends
with a return statement.

Comment out the code that is never reached in qlt_set_data_offset()
to avoid that static source code analysis tools report warnings for
this code.

Hi Bart,
Thanks for the patches. We will run regression with these changes and ack
if everything goes through fine.

Hello Saurav,
That sounds great. Are there perhaps already any results available from
the regression tests ?
Thanks,

Hi Bart,
Changes are going through our 12 week regression cycle and we will update
the status.

Hello Himanshu,
Thank you for the feedback. Since other qla2xxx driver patches have been
accepted upstream after my patch series had been posted I think the
patches should be reposted. Would you prefer to do that or do you
perhaps prefer that I repost that series ?
Bart.
