From dec63a4dec2d6d01346fd5d96062e67c0636852b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 15 Mar 2016 14:53:29 -0700 Subject: [PATCH] paride: make 'verbose' parameter an 'int' again gcc-6.0 found an ancient bug in the paride driver, which had a "module_param(verbose, bool, 0);" since before 2.6.12, but actually uses it to accept '0', '1' or '2' as arguments: drivers/block/paride/pd.c: In function 'pd_init_dev_parms': drivers/block/paride/pd.c:298:29: warning: comparison of constant '1' with boolean expression is always false [-Wbool-compare] #define DBMSG(msg) ((verbose>1)?(msg):NULL) In 2012, Rusty did a cleanup patch that also changed the type of the variable to 'bool', which introduced what is now a gcc warning. This changes the type back to 'int' and adapts the module_param() line instead, so it should work as documented in case anyone ever cares about running the ancient driver with debugging.
