From: Ondrej Zary Date: Wed, 9 Nov 2005 23:25:15 +0000 (+0100) Subject: [PATCH] ide-floppy: software eject not working with LS-120 drive X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=07203f6471a11f4eda48acbe528c0ce4704ad42c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [PATCH] ide-floppy: software eject not working with LS-120 drive The problem (eject not working on ATAPI LS-120 drive) is caused by idefloppy_ioctl() function which *first* tries generic_ide_ioctl() and *only* if it fails with -EINVAL, proceeds with the specific ioctls. The generic eject command fails with something other than -EINVAL and the specific one is never executed. This patch fixes it by first going through the internal ioctls and only trying generic_ide_ioctl() if none of them matches.
