From 7b836d84435e887727f16521ece721e6a75984a5 Mon Sep 17 00:00:00 2001 From: Viacheslav Ovsiienko Date: Mon, 13 Jan 2020 14:22:37 +0000 Subject: [PATCH] net/mlx5: fix doorbell register offset type The doorbell register is mapped using mmap() and offset must have off_t instead of unsigned int. Bug is not critical due to only least significant bits of offset are currently tested to determine mapping mode.
