From b22b4037a013e9ce77cec79d95fdcdc9bece0955 Mon Sep 17 00:00:00 2001 From: Manoj Kumar Date: Wed, 21 Oct 2015 15:15:30 -0500 Subject: [PATCH] cxlflash: Fix to double the delay each time The operator used to double the master context response delay is incorrect and does not result in delay doubling. To fix, use a left shift instead of the XOR operator. Reported-by: Tomas Henzl Signed-off-by: Matthew R. Ochs Signed-off-by: Manoj N.
