Subject: [PATCH] coresight: etm4x: Make etm4_remove_dev() return void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
etm4_remove_dev() returned zero unconditionally. Make it return void
instead, which makes it clear in the callers that there is no error to
handle. Simplify etm4_remove_platform_dev() accordingly.
