mtd: sharpslpart: Fix unsigned comparison to zero
commitf33113b542
upstream. The unsigned variable log_num is being assigned a return value from the call to sharpsl_nand_get_logical_num that can return -EINVAL. Detected using Coccinelle: ./drivers/mtd/parsers/sharpslpart.c:207:6-13: WARNING: Unsigned expression compared with zero: log_num > 0 Fixes:8a4580e4d2
