Subject: [PATCH] scd: Make SPRx32 pinpad work with PC/SC on Windows.
* scd/apdu.c (CM_IOCTL_GET_FEATURE_REQUEST): Use SCARD_CTL_CODE.
(SCARD_CTL_CODE): Define if not defined.
(reader_table_s): Add is_spr532.
(new_reader_slot): Clear it.
(check_pcsc_pinpad): Set it.
(pcsc_pinpad_verify, pcsc_pinpad_modify): Add fix for SPR532.
Signed-off-by: Werner Koch <wk@gnupg.org>
(cherry picked from commit 5c5e52df4b92e23045ac87abac09357de58920d4)
