Little clean up and move the do_irq on a deferrable work
Hmm, did the current solution cause any problems ?
I forgot to answer to this question. I find panics in the wifi and
I start to understand the code. So first of all I clean up the code
of the hif2 and move to a deferrable lock to avoid the release of the
lock. The bug remain and decide to take a look to the wext_ioctl.c and
I don't find any locking during remove of the device, so I change it too.
I don't mesaure the performance now. For reproduce the panic in the current
version of the kernel is simple:
request a scan from the user space and in the same time remove the device
with rfkill and the ioctl saw the priv data removed. I do it by hand, so
in android it can happen frequently just send the device to suspend when
the system in background scan for the network.
I post all the patches because we can discuss each modification and maybe
revert somenthing and provide better patches.
