Subject: usb: ehci-omap: drop unused ehci_read() function
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0cb46f8c7c72cb56badcf1f6b5f0ba1138a0f98c;p=linux.git

usb: ehci-omap: drop unused ehci_read() function

After moving the omap1 platform into generalized multiplatform
support on ARM, the kernel test robot points out a W=1 warning that
now shows up in more configurations:

drivers/usb/host/ehci-omap.c:64:19: warning: unused function 'ehci_read'

The function was last used 9 years ago and can just be removed.
