Subject: Blackfin: pm: drop irq save/restore in standby and suspend to mem callback
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=36e11ab23e22243b9c608a08c8d68ca5686b6c9b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Blackfin: pm: drop irq save/restore in standby and suspend to mem callback

Since linux-2.6.31, the kernel suspend framework will do disable_irq/enable_irq,
so save/restore irq in standby and suspend to mem callback should be dropped.
Otherwise the common code notices things are enabled and complains.
