[PATCH 05/11] omap-sham: move some flags to device context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dmitry Kasatkin <dmitry.kasatkin@xxxxxxxxx>

Couple of context flags have been moved to device flags.
IRQ and tasklet handlers does not need to access request
context anymore.
