If anyone has any objections, please let me know. ------------------ From: Krishna Kurapati commit ef8abc0ba49ce717e6bc4124e88e59982671f3b5 upstream. Leaving the USB BCR asserted prevents the associated GDSC to turn on. This blocks any subsequent attempts of probing the device, e.g. after a probe deferral, with the following showing in the log: [ 1.332226] usb30_prim_gdsc status stuck at 'off' Leave the BCR deasserted when exiting the driver to avoid this issue.
