Subject: [PATCH] sata_sil24: add hardreset
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=489ff4c7d167be954f715128790bd80d3c888322;p=linux-beck.git

[PATCH] sata_sil24: add hardreset

Now that libata is smart enough to handle both soft and hard resets,
add hardreset method.  Note that sil24 hardreset doesn't supply
signature; still, the new reset mechanism can make good use of it.
