From: Brian Norris Date: Sat, 16 Dec 2017 04:07:23 +0000 (-0800) Subject: ASoC: rt5514-spi: only enable wakeup when fully initialized X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=20220945b1a8e77c789dd4bb9aa1471b6e8695cc;p=linux.git ASoC: rt5514-spi: only enable wakeup when fully initialized If an rt5514-spi device is probed but the platform hasn't linked it in, we might never fully request the SPI IRQ, nor configure the rt5514 DSP, but we still might try to enable the SPI IRQ (enable_irq_wake()). This is bad, and among other things, can cause the interrupt to trigger every time we try to suspend the system (e.g., because the interrupt trigger setting was never set properly). Instead of setting our wakeup capabilities in the SPI driver probe routine, let's wait until we've actually requested the IRQ. Fixes issues seen on the "kevin" Chromebook (Samsung Chromebook Plus).
