Dan Carpenter 6548b0e5b8 [SCSI] megaraid: remove a spurious IRQ enable
We took this lock with spin_lock() so we should unlock it with
spin_unlock() instead of spin_unlock_irq().  This was introduced in
f2c8dc402b "[SCSI] megaraid_mbox: remove scsi_assign_lock usage".

adam radford c1529fa25e [SCSI] megaraid_sas: Add fpRead/WriteCapable, fpRead/WriteAcrossStripe checks
The following patch for megaraid_sas fixes the fastpath code decision
logic to use fpRead/WriteCapable, fpRead/WriteAcrossStripe flags
instead of the old logic.  This fixes a bug where fastpath writes
could be sent to a read only LD.

Paul Gortmaker acf3368ffb scsi: Fix up files implicitly depending on module.h inclusion
The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway.  We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

adam radford f575c5d3eb [SCSI] megaraid_sas: Fix instance access in megasas_reset_timer
The following patch for megaraid_sas will fix a potential bad pointer access
in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a
timeout.  megasas_build_io_fusion() sets SCp.ptr to be a struct
megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be
a struct megasas_cmd *, then trying to access cmd->instance, which is invalid.

Just loading instance from scmd->device->host->hostdata in
megasas_reset_timer() fixes the issue.
