This patch fixes gcc-3.4 cast-as-lvalue warnings in the 2.4.28-pre3
kernel's MTD drivers. The elan-104nc.c and sbc_gxx.c changes are
backports from the 2.6 kernel. The cfi_cmdset_0001.c and cfi_cmdset_0020.c
changes are new since the 2.6 code is different.

Btw, please don't use that other email address for me unless it's ultra-
secret company business which really has to be sent unencrypted via
their STARTTLS-incapable mail servers instead of via my secure ones. I
suppose I should fix MAINTAINERS accordingly...
