Subject: [PATCH] usb: typec: fusb302: Fix an undefined reference to
'extcon_get_state'
commit 547fc228755d79af648898187e7831a825d4f42c upstream.
Fixes the following compile error:
drivers/usb/typec/tcpm/fusb302.o: In function `tcpm_get_current_limit':
fusb302.c:(.text+0x3ee): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x422): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x450): undefined reference to `extcon_get_state'
fusb302.c:(.text+0x48c): undefined reference to `extcon_get_state'
drivers/usb/typec/tcpm/fusb302.o: In function `fusb302_probe':
fusb302.c:(.text+0x980): undefined reference to `extcon_get_extcon_dev'
make: *** [vmlinux] Error 1
It is because EXTCON is build as a module, but FUSB302 is not.
