From: Ben Dooks Date: Thu, 1 Oct 2009 22:44:16 +0000 (-0700) Subject: s3cmci: fix direct write to interrupt mask X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6130aeffd93d342e72ca85cfd335d066f680792;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git s3cmci: fix direct write to interrupt mask The clear_imask() call should be used to clear the interrupt mask register, as it may end up clearing the SDIO interrupt bit if this is enabled. Change all writes of zero to SDIIMSK register to use clear_imask() ready for the SDIO updates.
