From c064de86d2a3909222d5996c5047f64c7a8f791b Mon Sep 17 00:00:00 2001 From: Magnus Lindholm Date: Wed, 13 Nov 2024 23:51:49 +0100 Subject: [PATCH 01/14] scsi: qla1280: Fix hw revision numbering for ISP1020/1040 Fix the hardware revision numbering for Qlogic ISP1020/1040 boards. HWMASK suggests that the revision number only needs four bits, this is consistent with how NetBSD does things in their ISP driver. Verified on a IPS1040B which is seen as rev 5 not as BIT_4.

charset=UTF-8 Content-Transfer-Encoding: 8bit After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/ufs to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

The current UFS BSG code calls ufshcd_send_uic_cmd() directly, with which the second interrupt, i.e., UIC Power Mode interrupt, shall be treated as unhandled interrupt. In addition, after the UIC command is completed, user layer application has to poll UniPro and/or M-PHY state machine to confirm the power mode change is finished. Add a new wrapper function ufshcd_send_bsg_uic_cmd() and call it from ufs_bsg_request() so that if a UIC SET command is targeting the PA_PWRMODE attribute it can be redirected to ufshcd_uic_pwr_ctrl().

But they are not dropping that reference count after ufshcd_remove() to balance the refcount. So drop the reference count by calling pm_runtime_put_noidle() after ufshcd_remove(). Since the behavior is applicable to all glue drivers, move the PM handling to ufshcd_pltfrm_remove().
