[Spice-devel] [PATCH 07/12] libcacard: Fix bug detected with 'smatch'

[marcandre.lureau at redhat.com]

From: Thomas Huth <thuth at linux.vnet.ibm.com>

'smatch' complains about two bugs and one style issue in card_7816.c:

libcacard/card_7816.c:273 vcard_apdu_set_length() warn: should this be a bitwise op?
libcacard/card_7816.c:295 vcard_apdu_set_length() warn: should this be a bitwise op?
libcacard/card_7816.c:661 vcard7816_vm_process_apdu() warn: inconsistent indenting

... and indeed, the code seems to be wrong here. Let's fix this
by using a bitwise OR instead of logical OR and by indenting
the code with the right level.
