From 9761536e1d9e9e1f325fb04d4ad46b15a39eb94a Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 29 Sep 2014 16:08:26 -0700 Subject: debugfs: Have debugfs_print_regs32() return void The seq_printf() will soon just return void, and seq_has_overflowed() should be used instead to see if the seq can no longer accept input. As the return value of debugfs_print_regs32() has no users and the seq_file descriptor should be checked with seq_has_overflowed() instead of return values of functions, it is better to just have debugfs_print_regs32() also return void.
