From 1d4d5b325315f064e8cd4efaefbe50cdda0357c7 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 17 Apr 2005 10:57:20 -0700 Subject: [PATCH] [PATCH] revert fs/char_dev.c CONFIG_BASE_FULL change This reverts a fs/char_dev.c patch that was merged into BK on March 3. The problem is that it breaks things ... __register_chrdev_region() has a block of code, commented "temporary" for over two years now, which fails rudely during PCMCIA initialization or other register_chrdev() calls, because it doesn't "degrade to linked list". This keeps whole subsystems from working. A real fix to that "temporary" code should be possible, using some better scheme to allocate major numbers, but it's not something I want to spend time on just now.
