Subject[PATCH v2] ata: ahci_st: fixup layering violations / drvdata errors
Date
Hi Tejun / Brian,

I tested the initial version of this patch (see http://patchwork.ozlabs.org/patch/459422/)
on stih410 hardware, however it introduced a NULL ptr dereference, as plat_data
isn't set until ahci_platform_init_host() but plat_data was being used before
this in the st_ahci_probe_resets and st_ahci_deassert_resets() functions.

Also the original patch had a conflict with a patch which Tejun has already
taken of mine
(see here http://lists.infradead.org/pipermail/linux-arm-kernel/2015-March/326900.html).

So this V2 fixes the conflict, and re-works st_ahci_probe_resets and
st_ahci_deassert_resets functions to take struct ahci_host_priv *hpriv as
a parameter.

Brian - I'm not sure of the correct patch etiquette here. Currently I have
taken authorship of the patch and added a "Suggested-by" tag on the V2.
Maybe I should have also kept your "Signed-off-by" or done something else?
Please let me know if this is OK or if you would like something changed.

regards,

Peter.

Changes since v1:
- Rework st_ahci_deassert_resets and st_ahci_probe_resets
- Fix conflict with "st_configure_oob must be called after IP is clocked." patch
