[RFA] remote-e7000.c warnings

[Elena Zannoni]

This patch removes warnings when building remote-e7000.c.  (On Linux
7.0) Since this file gets build with target=sh-elf, I was getting
tired of all the warnings on the screen.
But then I saw the FIXME in the Makefile, so I am not sure what to do.
# FIXME: For the SH target, remote-e7000 contains numerous -Wformat
# warnings.  Since the fixes involve modifications to the code that
# handles the SH remote protocol the changes need to be tested against
# an SH board before they can be committed. cagney 1999-09-01.

Ideas?
Can anybody test this with a real connection?

Here is the patch anyway.

	* remote-e7000.c (fetch_regs_from_dump): If register set is null,
	generate an internal error.
	(e7000_fetch_registers): Initialize variable 'wanted'.
	(e7000_wait): Initialize variable 'wanted_nopc'.
	(e7000_store_register): Fix sprintf compiler warnings.
	(sub2_from_pc): Ditto.
	(e7000_open): Close the descriptor, not the name.
	(e7000_load): Fix compiler warnings.
	(sub2_from_pc): Ditto.
