From c904375d4b15122c225c1073fd7a56bd541b0ce5 Mon Sep 17 00:00:00 2001 From: Frans Klaver Date: Thu, 6 Nov 2014 21:10:17 +0100 Subject: [PATCH] serial: 8250_core: actually limit char reads to max_count In serial8250_rx_chars(), max_count is set to 256. Due to the post-decrement operator used in the while() condition, the maximum number of iterations actually 257. This is not a problem, but it is mildly surprising if you're debugging. Use pre-decrement instead. Signed-off-by: Frans Klaver Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
