ALSA: seq: Set upper limit of processed events

2022-01-27T08:00:58+00:00

[ Upstream commit 6fadb494a638d8b8a55864ecc6ac58194f03f327 ] Currently ALSA sequencer core tries to process the queued events as much as possible when they become dispatchable. If applications try to queue too massive events to be processed at the very same timing, the sequencer core would still try to process such all events, either in the interrupt context or via some notifier; in either away, it might be a cause of RCU stall or such problems. As a potential workaround for those problems, this patch adds the upper limit of the amount of events to be processed. The remaining events are processed in the next batch, so they won't be lost. For the time being, it's limited up to 1000 events per queue, which should be high enough for any normal usages.

ASoC: samsung: idma: Check of ioremap return value

[ Upstream commit 3ecb46755eb85456b459a1a9f952c52986bce8ec ] Because of the potential failure of the ioremap(), the buf->area could be NULL. Therefore, we need to check it and return -ENOMEM in order to transfer the error.
