From 4266d21669de62cf3fb6774f7d404c1eb95a5ab3 Mon Sep 17 00:00:00 2001 From: Tharun Kumar P Date: Tue, 4 Apr 2023 22:46:12 +0530 Subject: spi: mchp-pci1xxxx: Fix SPI transactions not working after suspend and resume pci1xxxx_spi_resume API masks SPI interrupt bit which prohibits interrupt from coming to the host at the end of the transaction after suspend-resume. This patch unmasks this bit at resume.
