+Subject: [PATCH] Fix format-truncation compile failure by typecasting USB IDs<br>
+ (#8250)<br>
+<br>
+This patch adds safe_atoux16 for parsing an unsigned hexadecimal 16bit int, and<br>
+uses that for parsing USB device and vendor IDs.<br>
+<br>
+This fixes a compile error with gcc-8 because while we know that USB IDs are 2 bytes,<br>
+the compiler does not know that.<br>
+<br>
+../src/udev/udev-builtin-hwdb.c:80:38: error: '%04X' directive output may be<br>
+truncated writing between 4 and 8 bytes into a region of size between 2 and 6<br>
+[-Werror=format-truncation=]<br>
+<br>
+Upstream-Status: Backport [<a href="https://github.com/systemd/systemd/commit/5547c12503a683290eaed47954ffcfb2d1bc03cd" rel="noreferrer" target="_blank">https://github.com/systemd/systemd/commit/5547c12503a683290eaed47954ffcfb2d1bc03cd</a>]<br>
