Hi,
Please find the corrected patch.
This patch fixes the following issues in drivers/pcmcia/au1000_generic.c.
1. On the error path, skt would not contain a valid value for the
first iteration (skt is masked by uninitialized automatic variable
skt) which would cause a crash.
2. does not do hw_shutdown() for 0th element of PCMCIA_SOCKET.
Applies cleanly to 2.6.18-rc6, rc7, 2.6.18, and 2.6.19-rc1
Regards,
Om.
