A Coverity robot reported an integer handling issue (OVERFLOW_BEFORE_WIDEN) in the potentially overflowing expression: (mtd_div_by_ws(mtd->size, mtd) - mtd_div_by_ws(offs, mtd)) * mtd_oobavail(mtd, ops) While such overflow will certainly never happen due to the numbers handled, it is cleaner to fix this operation anyway. The problem is that all the maths include 32-bit quantities, while the result is stored in an explicit 64-bit value. As maxooblen will just be compared with a size_t, let's change the type of the variable to a size_t. This will not fix anything but will clarify a bit the situation. Then, do an explicit cast to fix Coverity warning. Addresses-Coverity-ID: 184180 ("Integer handling issues") Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> |
