From d6f2f6c6e341998fcaf4e04c0308c24d86bece51 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Tue, 12 Sep 2023 08:27:41 +0900 Subject: [PATCH] scsi: pm8001: Simplify pm8001_chip_interrupt_enable/disable() pm8001_chip_msix_interrupt_enable() and pm8001_chip_msix_interrupt_disable() are always cold with the vector argument equal to 0. This allows simplifying the code for these functions. With this change, the functions are simple enough and can be removed by open coding them directly in pm8001_chip_interrupt_enable() and pm8001_chip_interrupt_disable(). Also do the same for the functions pm8001_chip_intx_interrupt_enable() and pm8001_chip_intx_interrupt_disable() and remove these functions.
