scsi: ufs: Un-inline ufshcd_vops_device_reset function
Browse files Browse the repository at this point in the history
More and more statements are being added to ufshcd_vops_device_reset() and
this function is being called from multiple locations in the driver.
Un-inline the function to allow the compiler to make better decisions.
