Subject: [PATCH 1/3] module: Prepare to convert all module_param_call() prototypes
Date: Tue, 17 Oct 2017 19:04:41 -0700 [thread overview]
Message-ID: <1508292283-140003-2-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1508292283-140003-1-git-send-email-keescook@chromium.org>
After actually converting all module_param_call() function prototypes, we
no longer need to do a tricky sizeof(func(thing)) type-check. Remove it.
