From 85a624403c77c3f074931aefdfced59f61b668cb Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Thu, 13 Oct 2016 16:13:55 -0700 Subject: ethtool: silence warning on bit loss Sparse was complaining when we went to prototype some code using ethtool_cmd_speed_set and SPEED_100000, which uses the upper 16 bits of __u32 speed for the first time. CHECK ... .../uapi/linux/ethtool.h:123:28: warning: cast truncates bits from constant value (186a0 becomes 86a0) The warning is actually bogus, as no bits are really lost, but we can get rid of the sparse warning with this one small change.
