5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Bart Van Assche <bvanassche@xxxxxxx> [ Upstream commit 46c97948e9b5bc8b67fd72741a2fe723ac1d14d7 ] Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007204618.2196847-10-bvanassche@xxxxxxx Signed-off-by: Bart Van Assche <bvanassche@xxxxxxx> Signed-off-by: Martin K.
