pcmcia: Remove NEC VRC4173 CARDU
The driver was introduced in 2.6.11 in the pre-git times with commit "[PATCH] mips: vR41xx updates". However, even back then, this driver was not able to be compiled, as a number of udpates had been missing from this driver: It still provided a "->get_io_map" callback (removed for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t (removed for v2.5.72). Moreover, this driver failed to be brought and be kept up to date; e.g. it still provides '->register_callback', incompatible with a change committed for v2.6.14 in commit7f316b033b("[PATCH] pcmcia: remove socket register_callback"), and uses INIT_WORK() with three arguments which was removed in commit65f27f3844("WorkStruct: Pass the work_struct pointer instead of context data") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> [linux@dominikbrodowski.net: rewrite commit message] Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
