The main body of this function is an if { } else if { } pair of blocks.
Previously there was int button at the top level scope which is used
only in the first block, and a redeclaration of int button inside the
second block. Since there's no overlap in the code paths for the
two uses of button, move the one from the outer block into the first
block to help the programmer more quickly determine they are unrelated
usages, and to silence the gcc warning of:
xkbActions.c: In function '_XkbFilterDeviceBtn':
xkbActions.c:999:6: warning: declaration of 'button' shadows a previous local
xkbActions.c:955:6: warning: shadowed declaration is here
For consistency, move DeviceIntPtr dev declarations as well that are
used in the same way.
