From 89bb46d02046b59c1de3d2e92680f3a1062750d0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 28 Feb 2012 09:57:59 +0300 Subject: [PATCH] Bluetooth: change min_t() cast in hci_reassembly() "count" is type int so the cast to __u16 truncates the high bits away and triggers a Smatch static checker warning. It looks like a high value of count could cause a forever loop, but I didn't follow it through to see if count is capped somewhere.
