Subject: ide-floppy: remove IDEFLOPPY_DEBUG_INFO
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f373bd820dd80ae079537afb9db511b8802bb9f7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ide-floppy: remove IDEFLOPPY_DEBUG_INFO

This info is already available through ioctl() and /proc

Bart:
- dump 'gcw.packet_size' for unsupported packet sizes
