From 897df60c16d54ad515a3d0887edab5c63da06d1f Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam mani@kernel.org Date: Mon, 11 Nov 2024 23:18:34 +0530 Subject: [PATCH] scsi: ufs: pltfrm: Dellocate HBA during ufshcd_pltfrm_remove()

This will ensure that the scsi host is cleaned up properly using scsi_host_dev_release(). Otherwise, it may lead to memory leaks.
