pcmcia: introduce autoconfiguration feature
Introduce an autoconfiguration feature to set certain values in pcmcia_loop_config(), instead of copying the same code over and over in each PCMCIA driver. At first, introduce the following options: CONF_AUTO_CHECK_VCC check or matching Vcc entry CONF_AUTO_SET_VPP set Vpp CONF_AUTO_AUDIO enable the speaker line CC: netdev@vger.kernel.org CC: linux-wireless@vger.kernel.org CC: linux-ide@vger.kernel.org CC: linux-usb@vger.kernel.org CC: laforge@gnumonks.org CC: linux-mtd@lists.infradead.org CC: alsa-devel@alsa-project.org CC: linux-serial@vger.kernel.org CC: Jiri Kosina <jkosina@suse.cz> CC: linux-scsi@vger.kernel.org Acked-by: Gustavo F.
