Alexey Khoroshilov 4c229df0b1 staging: sbe-2t3e3: fix error handling in t3e3_init_channel()
t3e3_init_channel() incorrectly handles errors in several places:
it returns zero and does not deallocate all required resources.
The patch fixes that places.

Found by Linux Driver Verification project (linuxtesting.org).

Devendra Naga a00979cccb staging: sbe-2t3e3: use -ve error return codes in dc_init_descriptor_list
the dc_init_descriptor_list actually returns a +ve error return codes,
which is abnormal as other functions in kernel return -ve error codes on
failure. so replace the return codes of this function with -ve values
to make the consistency with the other functions in kernel.

Also make the dc_init_descriptor_list static as its never called
anywhere except in this file and move the function prototype from the
headerfile into the c file as its referred only in this c file.

Devendra Naga 1cdb9c7c1d staging/sbe-2t3e3: use module_pci_driver macro
the _init and _exit functions do nothing but pci_register_driver,
and pci_unregister_driver,

so replace these and also the module _init and _exit
macros with the module_pci_driver macro.

Krzysztof Halasa 921a86e0e3 Staging: Add SBE 2T3E3 WAN driver
This is a driver for SBE Inc.'s dual port T3/E3 WAN cards. Based on
their original GPLed driver.

The original driver tarball is now accessible at
http://userweb.kernel.org/~chris/SBE_2T3_Linux_2.0c.tgz

It needs at least a new generic HDLC setup code (not yet written) before
moving to drivers/net/wan.
