Replace the request_mem_region + ioremap calls by the
devm_ioremap_resource call which does the same things but with device
managed resources.

Did you build these patches?

Yes, I did.

There's several breakages due to them in
last night's next. I'm a little puzzled how they passed testing before
you submitted?
This one fails with:

drivers/usb/host/ohci-at91.c: In function 'usb_hcd_at91_probe':
drivers/usb/host/ohci-at91.c:157:36: error: 'dev' undeclared (first
use in this function)
hcd->regs = devm_ioremap_resource(dev, res);
^
drivers/usb/host/ohci-at91.c:157:36: note: each undeclared identifier
is reported only once for each function it appears in
drivers/usb/host/ohci-at91.c:157:41: error: 'res' undeclared (first
use in this function)
hcd->regs = devm_ioremap_resource(dev, res);

Actually this patch series depends on another patch :
"usb: ohci-at91: fix irq and iomem resource retrieval"
commit fb5f1834c3221e459324c6885eaad75429f722a5.

This patch was taken out to ease integration in 3.13-rc5.

Sorry, I should have stated it in my cover letter.

Which next are you using ?
I took a look at linux-next and the dev variable is declared.

There are more too, the original one I was bisecting for was the below
one, but the above hit first:

drivers/usb/host/ohci-at91.c: In function 'usb_hcd_at91_probe':
drivers/usb/host/ohci-at91.c:190:4: error: label 'err' used but not defined

drivers/usb/host/ohci-at91.c:97:13: warning: 'at91_stop_hc' defined
but not used [-Wunused-function]

These errors come from merge commit 99f14bd4d1b2a1b1b6cd508e08efdbc5e3919198.

There is a missing brace on the last retval test.

Best Regards,

Boris
Somewhat spectacular. Greg, can you please drop these until he's
sorted out his submission? :(
