commit aa8679736a82386551eb9f3ea0e6ebe2c0e99104 upstream.
Clang warns:
../drivers/scsi/qla4xxx/ql4_os.c:4148:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
if (ha->fw_dump)
^
../drivers/scsi/qla4xxx/ql4_os.c:4144:2: note: previous statement is

1 warning generated.This warning occurs because there is a space after the tab on this
line. Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.Fixes: 068237c87c64 ("[SCSI] qla4xxx: Capture minidump for ISP82XX on firmware failure")

commit 3fe3d2428b62822b7b030577cd612790bdd8c941 upstream.
The variable init_fw_cb is released twice, resulting in a double free
bug. The call to the function dma_free_coherent() before goto is removed to
get rid of potential double free.Fixes: 2a49a78ed3c8 ("[SCSI] qla4xxx: added IPv6 support.")

[ Upstream commit fee92f25777789d73e1936b91472e9c4644457c8 ]
On this error path we call qla4xxx_mem_free() and then the caller also
calls qla4xxx_free_adapter() which calls qla4xxx_mem_free(). It leads to a

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

We get 1 warning when build kernel with W=1:
drivers/scsi/qla4xxx/ql4_nx.c:1846:10: warning: no previous prototype for 'ql4_84xx_ipmdio_rd_reg' [-Wmissing-prototypes]In fact, this function is only used in the file in which it is declared
and don't need a declaration, but can be made static. This patch marks
this function with 'static'.Signed-off-by: Baoyou Xie

The qla4_83xx_rd_reg_indirect() function can fail when it is unable to
read a register, but not all callers check its return value before using
the register data, and gcc correctly warns about this:qla4xxx/ql4_83xx.c: In function 'qla4_83xx_process_reset_template':
qla4xxx/ql4_83xx.c:1073:36: warning: 'value' may be used uninitialized in this function

^Unfortunately, I don't see any helpful way to add proper error handling
for this case, and the failure scenario for rd_reg seems rather obscure,
so this bails out and makes the rd_reg accessor set the result to
0xffffffff so we at least get a predictable value.Signed-off-by: Arnd Bergmann

Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor
issues"* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits)

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags. We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.Signed-off-by: Christoph Hellwig
