From 95c6bff72b02ca084be60c08503d563e506b733f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 3 Jul 2023 17:17:45 +0300 Subject: cxl/mem: Fix a double shift bug The CXL_FW_CANCEL macro is used with set/test_bit() so it should be a bit number and not the shifted value. The original code is the equivalent of using BIT(BIT(0)) so it's 0x2 instead of 0x1. This has no effect on runtime because it's done consistently and nothing else was using the 0x2 bit.
