Merge branch 'for-3.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo: "Assorted libata updates. The most critical one is a fix for ahci oops during boot. Also, a new smallish platform ahci driver is added and sata_inic162x is marked clearly as experimental (it whines during boot too) as data corruption seems rather common on the device and it's unlikely to get any love in the foreseeable future. If the whining doesn't draw any attention, I think we'd probably be better of making the driver depend on BROKEN in a couple releases" This is v2 of this pull request with fixed dependencies for ahci_imx. * 'for-3.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: ahci_imx: depend on CONFIG_MFD_SYSCON ahci_imx: add ahci sata support on imx platforms ARM: imx6q: update the sata bits definitions of gpr13 ahci: fix Null pointer dereference in achi_host_active() libata: make it clear that sata_inic162x is experimental libata: replace strict_strtol() with kstrtol() ata: Fix DVD not dectected at some platform with Wellsburg PCH
