+Subject: Workaround patch for missing Python3 transition of the old
+ (pre-USB-storage) photo memory card support (pcardext) as this part builds
+ in Python3 environments but with pointer-related warnings which are fatal
+ errors for Ubuntu's build servers. The patch silences the warnings but the
+ memory card support is dropped in Python3 environments. This patch is
+ supplied by the HPLIP upstream developers and will be replaced by a more
+ proper solution in the next upstream release of HPLIP (see LP: #1275353)
