The root cause is that the _IOC macro can generate really large numbers,
which don't find into type int. My research into how GCC and Clang are
handling this at a low level didn't prove fruitful and surveying the
kernel tree shows that aside from here and a few places in the scsi
subsystem, everything that uses _IOC is at least of type 'unsigned int'.
Make that change here because as nothing in this function cares about
the signedness of the variable and it removes ambiguity, which is never
good when dealing with compilers.
While we're here, remove the unnecessary local variable ret (just return
-EINVAL and 0 directly).

In my attempt to hide the warnings because I thought they didn't serve
any purpose[1], Masahiro Yamada pointed out that {Read,Write}_hfc in
hci_pci.c should be using a standard register access method; otherwise,
the compiler will just remove the if statements.
For hfc_pci, use the versions of {Read,Write}_hfc found in
drivers/isdn/hardware/mISDN/hfc_pCI.h while converting pci_io to be
'void __iomem *' (and clean up ioremap) then remove the empty if
statements.
For hfc_sx, {Read,Write}_hfc are already use a proper register accessor
(inb, outb) so just remove the unnecessary if statements.

Pull regulator updates from Mark Brown:
"The biggest chunk of the regulator changes for this release outside of
the new drivers is the conversion of the fixed regulator to use the
GPIO descriptor API, there's a small addition to the GPIO API plus a
bunch of updates to board files to implement it. This is some really
welcome work from Linus Walleij that's had a bunch of review and has
been sitting in -next for a while so I'm fairly happy there's no major
issues.
- Helpers for overlapping linear ranges.
- Display opmode and consumer requested load in the regualtor_summary
file in debugfs, plus a fix there.
- Support for the fun and entertaining power off mechanism that the
pfuze100 hardware implements.
- Conversion of the fixed regulator API to use GPIO descriptors,

The TSENS driver currently only uses a limited set of registers from the TM
address space. So it was ok to map just that set of registers and call it
"map".
We'd now like to map a second set: SROT registers to introduce new
functionality. Rename the "map" field to a more appropriate "tm_map".
The 8960 doesn't have a clear split between TM and SROT registers. To avoid
complicating the data structure, it will switchover to using tm_map for its
maps.
There is no functional change with this patch.

Pull dma mapping updates from Christoph Hellwig:
"First batch of dma-mapping changes for 4.20.
There will be a second PR as some big changes were only applied just
before the end of the merge window, and I want to give them a few more
days in linux-next.
Summary:
- mostly more consolidation of the direct mapping code, including
converting over hexagon, and merging the coherent and non-coherent
code into a single dma_map_ops instance (me)
- cleanups for the dma_configure/dma_unconfigure callchains (me)
- better handling of dma_masks in odd setups (me, Alexander Duyck)
- better debugging of passing vmalloc address to the DMA API (Stephen
Boyd)
- CMA command line parsing fix (He Zhe)"

Pull arm64 updates from Catalin Marinas:
"Apart from some new arm64 features and clean-ups, this also contains
the core mmu_gather changes for tracking the levels of the page table
being cleared and a minor update to the generic

Summary:
- Core mmu_gather changes which allow tracking the levels of
page-table being cleared together with the arm64 low-level flushing
routines
- Support for the new ARMv8.5 PSTATE.SSBS bit which can be used to
mitigate Spectre-v4 dynamically without trapping to EL3 firmware
- Introduce COMPAT_SIGMINSTKSZ for use in compat_sys_sigaltstack
- Optimise emulation of MRS instructions to ID_* registers on ARMv8.4
- Support for Common Not Private (CnP) translations allowing threads
of the same CPU to share the TLB entries
- Accelerated crc32 routines
- Move swapper_pg_dir to the rodata section
- Trap WFI instruction executed in user space

flush_pool is leaked when flush bio size is zero

I noticed kmemleak report memory leak when run create/stop
md in a loop, backtrace:
[<000000001ca975e7>] mempool_create_node+0x86/0xd0
[<0000000095576bcd>] md_run+0x1057/0x1410 [md_mod]
[<000000007b45c5fc>] do_md_run+0x15/0x130 [md_mod]
[<000000001ede9ec0>] md_ioctl+0x1f49/0x25d0 [md_mod]
[<000000004142cacf>] blkdev_ioctl+0x680/0xd00
The root cause is we alloc mddev->flush_pool and
mddev->flush_bio_pool in md_run, but from do_md_stop
will not call into md_stop but __md_stop, move the
mempool_destroy to __md_stop fixes the problem for me.
The bug was introduced in 5a409b4f56d5, the fixes should go to
4.18+
