However, the patch breaks the idea of the endpoints -reference counting, which is the reason why the driver has been -refactored lately. - -Revert that commit and let snd_usb_endpoint_start() take care of the URB -cancellation again. As this function is called from both atomic and -non-atomic context, add a flag to denote whether the function may sleep. - -Signed-off-by: Daniel Mack -Cc: stable@kernel.org [3.5+] ---- - sound/usb/endpoint.c | 11 +++++++++-- - sound/usb/endpoint.h | 2 +- - sound/usb/pcm.c | 13 +++++-------- - 3 files changed, 15 insertions(+), 11 deletions(-) - -diff --git a/sound/usb/endpoint.c b/sound/usb/endpoint.c -index c411812..b896c55 100644 ---- a/sound/usb/endpoint.c -+++ b/sound/usb/endpoint.c -@@ -799,7 +799,9 @@ int snd_usb_endpoint_set_params(struct snd_usb_endpoint *ep, - /** - * snd_usb_endpoint_start: start an snd_usb_endpoint - * -- * @ep: the endpoint to start -+ * @ep: the endpoint to start -+ * @can_sleep: flag indicating whether the operation is executed in -+ * non-atomic context - * - * A call to this function will increment the use count of the endpoint. - * In case it is not already running, the URBs for this endpoint will be -@@ -809,7 +811,7 @@ int snd_usb_endpoint_set_params(struct snd_usb_endpoint *ep, - * - * Returns an error if the URB submission failed, 0 in all other cases. - */ --int snd_usb_endpoint_start(struct snd_usb_endpoint *ep) -+int snd_usb_endpoint_start(struct snd_usb_endpoint *ep, int can_sleep) - { - int err;
