Subject: Atoms from XIGetProperty are 32bits (#27657)
X-Git-Url: https://diplodocus.org/git/xorg-xinput/commitdiff_plain/87ec8d42c7f8e4e0613bcbe59fb2db991e1e4acb?ds=inline;hp=87ec8d42c7f8e4e0613bcbe59fb2db991e1e4acb

Atoms from XIGetProperty are 32bits (#27657)

A 32bit value must be dereferenced to correctly zero-extend an Atom
from XIGetProperty.  On 64bit systems, Atom is 64bits, so the final
Atom in a list will read garbage in the upper half of the Atom.
