Subject: alim15x3: use ->host_flags and ->udma_mask fields from ide_pci_device_t
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=283283070f2607ed759563613c044f96f1546834;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

alim15x3: use ->host_flags and ->udma_mask fields from ide_pci_device_t

* Make a local copy of ali15x3_chipset in alim15x3_init_one() and set
  ->host_flags / ->udma_mask according to the controller capabilities.

* Cleanup init_hwif_common_ali15x3().

* Bump driver version.
