[PATCH v3 0/10] qla2xxx: Fix various warnings reported by static source code analysis tools

[Bart Van Assche]

This patch series addresses several warnings reported by static source
code analysis tools for the qla2xxx driver (gcc (W=1), sparse (C=2) and
smatch (C=2 CHECK="smatch -p=kernel")). The patches in this series are:

0001-qla2xxx-Report-both-rsp_info-and-rsp_info_len.patch
0002-qla2xxx-Declare-local-functions-static.patch
0003-qla2xxx-Remove-set-but-not-used-variables.patch
0004-qla2xxx-Replace-two-macros-with-an-inline-function.patch
0005-qla2xxx-Remove-__constant_-prefix.patch
0006-qla2xxx-Avoid-that-sparse-complains-about-duplicate-.patch
0007-qla2xxx-Fix-sparse-annotations.patch
0008-qla2xxx-Remove-a-superfluous-test.patch
0009-qla2xxx-Remove-dead-code.patch
0010-qla2xxx-Avoid-that-sparse-complains-about-context-im.patch

Version 3 is a resend of the patches from v2 that are not yet upstream.

The changes compared to v1 of this series are:
- Rebased this patch series onto kernel v4.1-rc6.
- Also removed variable 'd2' in patch 3.
- Also remove the recently introduced dead code in patch 10.

[PATCH v3 01/10] qla2xxx: Report both rsp_info and rsp_info_len

[Bart Van Assche]

Let the debug statement in qlafx00_tm_iocb_entry() report both rsp_info
and rsp_info_len instead of reporting rsp_info_len twice.

[PATCH v3 04/10] qla2xxx: Replace two macros with an inline function

[Bart Van Assche]

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.

[PATCH v3 05/10] qla2xxx: Remove __constant_ prefix

[Bart Van Assche]

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.

[PATCH v3 07/10] qla2xxx: Fix sparse annotations

[Bart Van Assche]

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.

[PATCH v3 09/10] qla2xxx: Remove dead code

[Bart Van Assche]

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.

Re: [PATCH v3 05/10] qla2xxx: Remove __constant_ prefix

Could you please run checkpatch on stuff before sending it?  I know the
qla_iocb.c file is a mess with mixed tabs and spaces, but if you don't
convert the lines you touch to acceptable style it will trigger the
static checkers.  I've fixed this up.
