Subject: [PATCH] usb: fotg210: fix USB_EHCI_HCD dependency
Date: Wed, 16 Sep 2026 13:43:45 +0200 [thread overview]
Message-ID: <20260916114358.195465-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
When EHCI is a loadable module, the fotg210 HCD code cannot
be built-in:
s390-linux-ld: drivers/usb/fotg210/fotg210-hcd.o: in function `fotg210_hcd_reset':
fotg210-hcd.c:(.text+0x102): undefined reference to `ehci_setup'
Fix this using the same type of dependency that is already
used for the USB host support.
