Subject: ide: remove obsoleted "hdx=noautotune" kernel parameter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc12175ff2eadb0918d573169af88429440a21ae;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ide: remove obsoleted "hdx=noautotune" kernel parameter

Remove obsoleted "hdx=noautotune" kernel parameter
(it has been obsoleted since 1 Nov 2004).

Then make ide_hwif_t.autotune a single bit flag
and remove no longer needed IDE_TUNE_* defines.
