Note: I will not change/fix code with a problem like:
pkcs15.c:1033:3: warning: Value stored to 'r' is never read
r = sc_pkcs15_parse_df(p15card, df);
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The easy way to solve the warning is to just remove the affectation.
But that would hide the real problem: the return value is not checked.
