Subject: [PATCH 1/5] lib/test_free_pages.c: Pass a pointer to virt_to_page()
Date: Thu, 30 Jun 2022 10:41:20 +0200 [thread overview]
Message-ID: <20220630084124.691207-2-linus.walleij@linaro.org> (raw)
In-Reply-To: <20220630084124.691207-1-linus.walleij@linaro.org>
A pointer into virtual memory is represented by a (void *)
not an u32, so the compiler warns:
lib/test_free_pages.c:20:50: warning: passing argument 1
of 'virt_to_pfn' makes pointer from integer without a
cast [-Wint-conversion]
Fix this with an explicit cast.
