X-Git-Tag: omap-for-v3.7-rc1/fixes-cpufreq-signed~75^2~275
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b8d61d49b2437df3a0aef17d321948783d275bb3;p=pandora-kernel.git

Staging: ipack/bridges/tpci200: RCU protect slot_irq pointers.

In tpci200_request_irq as well as tpci200_free_irq we set and unset the
pointer to struct slot_irq.  This pointer is accessed in
tpci200_interrupt.  To ensure that the pointer is not freed after it has
been fetched in tpci200_interrupt() it is now protected through RCU.
