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.
