Subject: fix unusual sysfs behavior for pcmcia_socket
Date: Thu, 14 Oct 2004 04:55:02 +0000 [thread overview]
Message-ID: <20041014045502.GA14286@vrfy.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 204 bytes --]
All files in /sys/class/pcmcia_socket/pcmcia_socket0/* are unreadable
without a card inserted:
read(3, 0x9167858, 4096) = -1 ENODEV (No such device)
So we need to skip that step for now.
Thanks,
Kay
