      USB: fix coccinelle warnings · 2e30d14f
      Fengguang Wu authored 
      drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0, suggest !E
/c/kernel-tests/src/cocci/drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0

 Compare pointer-typed values to NULL rather than 0

Semantic patch information:
 This makes an effort to choose between !x and x == NULL.  !x is used
 if it has previously been used with the function used to initialize x.
 This relies on type information.  More type information can be obtained
 using the option -all_includes and the option -I to specify an
 include path.

      USB: remove DEFINE_PCI_DEVICE_TABLE macro · 2fd3f651

      Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro
is not preferred.

      xhci: replace xhci_write_64() with writeq() · 7dd09a1a
      Xenia Ragiadakou authored 
      Function xhci_write_64() is used to write 64bit xHC registers residing in MMIO.
On 32bit systems, xHC registers need to be written with 32bit accesses by
writing first the lower 32bits and then the higher 32bits. The header file
asm-generic/io-64-nonatomic-lo-hi.h ensures that on 32bit systems writeq() will
will write 64bit registers in 32bit chunks with low-high order.

Replace all calls to xhci_write_64() with calls to writeq().

This is done to reduce code duplication since 64bit low-high write logic
is already implemented and to take advantage of inherent "atomic" 64bit
write operations on 64bit systems.

Replace all calls to xhci_read_64() with calls to readq() and include
asm-generic/io-64-nonatomic-lo-hi.h header file, so that if the system
is not 64bit, readq() will read registers in 32bit chunks with low-high order.

is already implemented and to take advantage of inherent "atomic" 64bit
