powerpc: Fix signedness bug in update_flash_db()
[ Upstream commit 014704e6f54189a203cc14c7c0bb411b940241bc ]
The "count < sizeof(struct os_area_db)" comparison is type promoted to
size_t so negative values of "count" are treated as very high values
and we accidentally return success instead of a negative error code.
This doesn't really change runtime much but it fixes a static checker
warning.
