Subject: Sonypi: use synchronize_irq instead of sycnronize_sched
X-Git-Tag: v2.6.24-rc4~89^2~5
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3cb93db6e89bdffeae1f001bd87c9e96f9b634df;p=linux-2.6

Sonypi: use synchronize_irq instead of sycnronize_sched

We know exactly what IRQ we are using, so synchronize_irq()
suits much better. Plus synchronize_sched() will not work
for us in -rt kernels.
