From: H Hartley Sweeten <hartleys@visionengravers.com>
In sd_store_cache_type the symbol 'len' is declared twice. Remove the
second declaration to quiet the following sparse warning.
warning: symbol 'len' shadows an earlier one
In sd_probe the variable 'index' is declared as a u32. This variable is
used in a call to ida_get_new which is expecting an int *. Make the
variable an int to quiet the following sparse warning.
warning: incorrect type in argument 2 (different signedness)
There are 4 symbols in the file that are not exported and produce
the following sparse warnings.
warning: symbol 'sd_cdb_cache' was not declared. Should it be static?
warning: symbol 'sd_cdb_pool' was not declared. Should it be static?
warning: symbol 'sd_read_protection_type' was not declared. Should it be static?
warning: symbol 'sd_read_app_tag_own' was not declared. Should it be static?
Make them static to quiet the warnings.
