isp1760_stop() is never called in atomic context. The call chain ending up at isp1760_stop() is: [1] isp1760_stop() <- isp1760_shutdown() isp1760_shutdown() is set as ".shutdown" in struct hc_driver. isp1760_stop() is also set as ".stop" in hc_driver. These functions are not called in atomic context. Despite never getting called from atomic context, isp1760_stop() calls mdelay() to busily wait. This is not necessary and can be replaced with msleep() to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself.
