From abc5de8f4e68ea785e32b91e456f467d2a2fb7db Mon Sep 17 00:00:00 2001 From: Mikel Astiz Date: Wed, 11 Apr 2012 08:48:47 +0200 Subject: [PATCH] Bluetooth: Use unsigned int instead of signed int The involved values are all unsigned and thus unsigned int should be used instead of signed int. Assigning ~0 to a signed int results in -1, which is confusing and error-prone, while the code is trying to set the maximum value possible. The code still works because the C standard defines that unsigned comparison will be performed in these cases, when comparing an unsigned int and a signed int.
