YueHaibing f770e3bc23 usb: mtu3: fix dbginfo in qmu_tx_zlp_error_handler
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/mtu3/mtu3_qmu.c: In function 'qmu_tx_zlp_error_handler':
drivers/usb/mtu3/mtu3_qmu.c:385:22: warning:
 variable 'req' set but not used [-Wunused-but-set-variable]

It seems dbginfo original intention is print 'req' other than 'mreq'

Chunfeng Yun 4f7371314e usb: mtu3: remove QMU checksum
The QMU checksum calculation is redundant, mostly used by debug,
so remove it here.

Greg Kroah-Hartman 4c55a15774 USB: mtu3: Remove redundant license text
Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

Greg Kroah-Hartman 5fd54ace47 USB: add SPDX identifiers to all remaining files in drivers/usb/
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Arnd Bergmann 20ef800bab usb: mtu3: fix dma_addr_t printk output again
The support for 36-bit addresses originally came with an incorrect
printk format for dma addresses. Felipe changed the format string it
while applying, but the result was still incorrect, since we now have
to pass a pointer to the address instead of the integer value:

drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_tx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:261:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_rx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:300:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]

This fixes the printk argument accordingly.
