Wei WANG 1c9e55cda4 USB: usb-stor: realtek_cr: Fix compile error
To fix the compile error when CONFIG_PM_RUNTIME is not enabled,
move the declaration of us out of CONFIG_REALTEK_AUTOPM macro in rts51x_chip.

drivers/usb/storage/realtek_cr.c: In function 'realtek_cr_destructor':
drivers/usb/storage/realtek_cr.c:942:11: error: 'struct rts51x_chip' has no member named 'us'

Joe Perches 191648d03d usb: storage: Convert US_DEBUGP to usb_stor_dbg
Use a more current logging style with dev_printk
where possible.

o Convert uses of US_DEBUGP to usb_stor_dbg
o Add "struct us_data *" to usb_stor_dbg uses
o usb_stor_dbg now uses struct device */dev_vprint_emit
o Removed embedded function names
o Coalesce formats
o Remove trailing whitespace
o Remove useless OOM messages
o Remove useless function entry/exit logging
o Convert some US_DEBUGP uses to dev_info and dev_dbg

Object size is slightly reduced when debugging
is enabled, slightly increased with no debugging
because some initialization and removal messages
are now always emitted.

Sebastian Andrzej Siewior f61870ee6f usb: remove libusual
The "Low Performance USB Block driver" has been removed which a user of
libusual. Now we have only the usb-storage driver as the only driver in
tree. This makes libusual needless.
This patch removes libusal, fixes up all users. The usual-table is now
linked into usb-storage.
usb_usual.h remains in public include directory because some staging
users seem to need it.

Sebastian Andrzej Siewior b8db6d6402 usb/storage: redefine US_BULK_FLAG_IN and use it
US_BULK_FLAG_IN is defined as 1 and not used. The USB storage spec says
that bit 7 of flags within CBW defines the data direction. 1 is DATA-IN
(read from device) and 0 is the DATA-OUT. Bit 6 is obselete and bits 0-5
are reserved.
This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7
aka 0x80 and replaces the obvious users. In a following patch the
storage gadget will use it as well.

jwboyer@redhat.com 4898e07174 USB: ums_realtek: do not use stack memory for DMA in __do_config_autodelink
__do_config_autodelink passes the data variable to the transport function.
If the calling functions pass a stack variable, this will eventually trigger
a DMA-API debug backtrace for mapping stack memory in the DMA buffer.  Fix
this by calling kmemdup for the passed data instead.

This converts the drivers in drivers/usb/* to use the
module_usb_driver() macro which makes the code smaller and a bit

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
