Negative constant left-shift is undefined behaviour in the C standard, and
as such newer versions of clang (at least) warn against it. GCC supports it
for a long time, but it would be better to remove it and rely on defined
behaviour.
My understanding is "~(-1 << N)" in 2's complement is intended to generate
a bit pattern of zeroes ending with N '1' bits. The same can be achieved by
"(1 << N) - 1" in a well-defined way, so switch to it to remove the
warning.
Tested: building a kernel with generic SCSI tape, and checking basic
operations (mt status, mt eject) on a real LTO unit. Cannot test the osst
driver.

Add this functionality, placing the descriptor being read in the actual
data buffer in the bio.
That is, for both read and write descriptors query upiu, we are using the
job's request_payload. This in turn, is mapped back in user land to the
applicable sg_io_v4 xferp: dout_xferp for write descriptor, and din_xferp
for read descriptor.

When we had a write descriptor query upiu, we appended the descriptor right
after the bsg request. This was fine as the bsg driver allows to allocate
whatever buffer we needed in its job request.
Still, the proper way to deliver payload, however small (we only write
config descriptors of 144 bytes), is by using the job request payload data
buffer.
So change this ABI now, while ufs-bsg is still new, and nobody is actually
using it.

Resolution: keep HEAD, and delete the ufshcd_set_vccq_rail_unused() call
and corresponding error-handling code.
Clean up loose ends in a follow-up patch.
60f0187031c0 introduced a small power optimization: ignore the vccq load
specified in the UFSHC DT node when said host controller is connected to
specific Flash chips (currently, Samsung and Hynix).
Unfortunately, this optimization breaks UFS on systems where vccq powers
not only the Flash chip, but the host controller as well, such as APQ8098
MEDIABOX or MTP8998:

In my opinion, the rationale for the original patch is questionable. If
neither the UFSHC, nor the Flash chip, require any load from vccq, then
that power rail should simply not be specified at all in the DT.
Working around that fact in the driver is detrimental, as evidenced by the
failure to initialize the host controller on MSM8998.

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of
0xFFFF blocks. That looks bogus, especially for a device with a
4096-byte physical block size.
Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's
reported physical block size.
To make the sanity checking conditionals more readable--and to
facilitate printing warnings--relocate the checking to a helper
function. No functional change aside from the printks.

commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate
enum for the fip_mode that shall be used during initialisation handling
until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That
change was incomplete and gcc quietly converted in various places between
the fip_mode and the fip_state enum values with implicit enum conversions,
which fortunately cannot cause any issues in the actual code's execution.
clang however warns about these implicit enum conversions in the scsi
drivers. This commit consolidates the use of the two enums, guided by
clang's enum-conversion warnings.
This commit now completes the use of the fip_mode: It expects and uses
fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls
fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It
also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to
indicate these two enums are distinct.

This patch fixes LUN discovery when loop ID is not yet assigned by the

The null check on pointer sess and the subsequent call is redundant as sess
is null on all the the paths that lead to the out_term2 label. Hence the
null check and the call can be removed. Also remove the redundant setting
of sess to NULL as this is not required now.

When sending an srb with qla2x00_start_sp, the sp can complete and be freed
by the time we log the debug message saying we sent it. This can cause a
panic if sp gets reused quickly or when running a kernel that poisons freed
memory.
This was partially fixed by (not every case was addressed):

Add HI3670 SoC UFS driver support by extending the common ufs-hisi
driver. One major difference between HI3660 ad HI3670 SoCs interms of UFS
is the PHY. HI3670 has a 10nm variant PHY and hence this parameter is used
to distinguish the configuration.

Add devicetree binding for HI3670 UFS controller. HI3760 SoC is very
similar to HI3660 SoC with almost same IPs. Only major difference in terms
of UFS is the PHY. HI3670 has 10nm PHY. But since the original driver
(HI3660 UFS) cannot make HI3670 UFS functional, a separate compatible
is added for HI3670 without any fallback.

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
As prom_name is not used for anything else, remove it.

Commit b2bff6ceb61a9 ("[SCSI] sd: Quiesce mode sense error messages")
added the macro sd_first_printk(). The macro takes "sdsk" as argument
but dereferences "sdkp". This hasn't caused any real issues since all
callers of sd_first_printk() have an sdkp. But fix the typo.
