[Qemu-devel] [PATCH] libcacard: Fix cppcheck warning and remove unneeded code

[Stefan Weil]

The local function vcard_emul_alloc_arrays always returned PR_TRUE.
Therefore cppcheck complained about code which handled the
non-existent PR_FALSE case.

Remove the function's return value and the dead code.
