From 222b9f933a76b127a073f45278d2b0199587e8ce Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Sun, 26 Mar 2006 01:37:31 -0800 Subject: [PATCH] tlclk: fix handling of device major tlclk calls register_chrdev() and permits register_chrdev() to allocate the major, but it promptly forgets what that major was. So if there's no hardware present you still get "telco_clock" appearing in /proc/devices and, I assume, an oops reading /proc/devices if tlclk was a module. Fix. Mark, I'd suggest that that we not call register_chrdev() until _after_ we've established that the hardware is present.
