From 104529661b645295903c5007ae632d2dd4029254 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 16 May 2013 11:11:08 +0300 Subject: [PATCH] pktcdvd: silence static checker warning Static checkers complain about widening the binary "not" operations here because sectors are u64 and "(pd)->settings.size" is unsigned int. It unintentionally clears the high 32 bits of the sector. This means that the driver won't work for devices with over 2TB of space. Since this is a DVD drive, we're unlikely to reach that limit, but we may as well silence the warning.
