Subject[PATCH -next] mtd: sharpslpart: Fix unsigned comparison to zero
Date
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: 8a4580e4d298 ("mtd: sharpslpart: Add sharpslpart partition parser")
