Subject: ide: mask interrupt in ide_config_drive_speed()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e5403bff8a4018240f012fd4c7afa24c2e75b469;p=deliverable%2Flinux.git

ide: mask interrupt in ide_config_drive_speed()

Apparently, there is no sense in unmasking IRQ on the controller when you call
disable_irq_nosync() before doing this, set the nIEN bit afterwards, and then
unmask IRQ again after the command completion, hence 0 passed to SELECT_MASK()
before issuing the command in ide_config_drive_speed() is probably just a typo.
