Subject: [PATCH] usb: ehci-omap: drop unused ehci_read() function
Git-commit: 0cb46f8c7c72cb56badcf1f6b5f0ba1138a0f98c
Patch-mainline: v5.19-rc1
References: git-fixes
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.
Fixes: 87425ad36330 ("USB: ehci-omap: Remove PHY reset handling code")
