Subject: [PATCH v3] binder: remove redundant variable page_addr
From: Colin Ian King <colin.i.king@...el.com>
Variable page_addr is being assigned a value that is never read. The
variable is redundant and can be removed.
Cleans up clang scan build warning:
warning: Value stored to 'page_addr' is never read [deadcode.DeadStores]
Signed-off-by: Colin Ian King <colin.i.king@...el.com>
Fixes: 162c79731448 ("binder: avoid user addresses in debug logs")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202312060851.cudv98wG-lkp@intel.com/
Acked-by: Carlos Llamas <cmllamas@...gle.com>
