[PATCH 4.9 14/31] rt2x00: Fix incorrect usage of CONFIG_RT2X00_LIB_USB

From: Greg Kroah-Hartman
Date: Sun Apr 16 2017 - 04:05:09 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Vishal Thanki <vishalthanki@xxxxxxxxx>

commit a083c8fd277b4122c804f18ec8c84165f345c71c upstream.

In device removal routine, usage of "#ifdef CONFIG_RT2X00_LIB_USB"
will not cover the case when it is configured as module. This will
omit the entire if-block which does cleanup of URBs and cancellation
of pending work. Changing the #ifdef to #if IS_ENABLED() to fix it.
