Subject: USB: core: remove set but not used variable 'udev'
X-Git-Tag: v4.20-rc1~109^2~13
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c36e96bd259d5ec1e73c2cbfdc3ef935e6b0f830;p=linux-block.git

USB: core: remove set but not used variable 'udev'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/core/driver.c: In function 'usb_driver_claim_interface':
drivers/usb/core/driver.c:513:21: warning:
 variable 'udev' set but not used [-Wunused-but-set-variable]

Since commit c183813fcee44a24 ("USB: remove LPM management from
usb_driver_claim_interface()"), 'udev' is not used.
