usb: gadget: u_bam: do runtime_put even if BAM channel was not opened (2913747e) · Commits · e / devices / android_kernel_xiaomi_markw

gbam_disconnect_work returns without doing a put, in the case where bam channel was not opened successfully. This leads to a runtime mismatch and USB not entering LPM again. Fix this by making sure that we do runtime_put in above mentioned case. Change-Id: Ic05f0ddf7ede3ad680726b9360a5d26ebf35772a Signed-off-by:
