From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 19:39:32 +0000 (+0200) Subject: ide: make ide_pc_intr() static X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa5d2de7b080873f6d9ac3aede423c9713bf0caa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ide: make ide_pc_intr() static * Always use ide_pc_intr as a handler in ide_pc_intr(). * Remove no longer used ide*_pc_intr() and 'handler' argument from ide_{transfer_pc,pc_intr}(). * Make ide_pc_intr() static. There should be no functional changes caused by this patch.
