Subject: MFD: mutex from ISR in ezx-pcap?
Date: Mon, 29 Jun 2009 21:34:54 +0200 [thread overview]
Message-ID: <4A49175E.3020409@gmail.com> (raw)
Hi,
pcap_adc_irq tries to perform non-atomic operations in ISR which is not
allowed. Above that, it may deadlock.
Since all the operations there (read, write, mutex locking) may sleep,
any objections to convert the ISR contents to a workqueue?
