Subject: pata_artop: fix UDMA5 for AEC6280[R] and UDMA6 for AEC6880[R]
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=be456b77ffbd3983b5da8eff49a70a701333f68b;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

pata_artop: fix UDMA5 for AEC6280[R] and UDMA6 for AEC6880[R]

Maximum supported UDMA mode for AEC6280[R] is UDMA5 (not UDMA4)
and for AEC6880[R] it is UDMA6 (not UDMA5):

* Fix the problem by adding missing struct ata_port_info to artop_init_one().

* Use the right naming (s/626/628/).

* Bump driver version.

Fixes IDE->libata regression, problem was never present in IDE aec62xx driver.
