From bbc3925cf696422492ebdaba386e61450fa2294c Mon Sep 17 00:00:00 2001 From: luo penghao Date: Thu, 21 Oct 2021 08:46:21 +0100 Subject: cdrom: Remove redundant variable and its assignment Variable is not used in functions, and its assignment is redundant too. So it should be deleted. Also the inner-most set of parentheses is no longer needed. The clang_analyzer complains as follows: drivers/cdrom/cdrom.c:877: warning: Although the value stored to 'ret' is used in the enclosing expression, the value is never actually read from 'ret'.
