From 9b200b02a6c9cddca5132d64aa41156bbcddcbaa Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 23 Jun 2005 21:06:56 -0700 Subject: [PATCH] [SLIP]: Simplify sl_free_bufs() We can avoid assignments to the local variable 'tmp' and actually get rid of tmp alltogether in sl_free_bufs(). This patch does that. This is safe since both kfree() and slhc_free() handles NULL pointers gracefully. Signed-off-by: Jesper Juhl Signed-off-by: David S.
