From 42d22098127d6384f789107f59caae87d7520fc4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 18 Sep 2019 21:59:02 +0200 Subject: Bluetooth: btusb: avoid unused function warning The btusb_rtl_cmd_timeout() function is used inside of an ifdef, leading to a warning when this part is hidden from the compiler: drivers/bluetooth/btusb.c:530:13: error: unused function 'btusb_rtl_cmd_timeout' [-Werror,-Wunused-function] Use an IS_ENABLED() check instead so the compiler can see the code and then discard it silently.
