Subject: h8300:let the checker know that size_t is ulong
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1b803a357d520164404c6262710049b09b93ed5a;p=openwrt%2Fstaging%2Fblogic.git

h8300:let the checker know that size_t is ulong

All 64bit archs use unsigned long for size_t and most 32bit
archs use 'unsigned int'. By default, this is what is assumed
by sparse.

However, on h8300 (a 32bit arch) size_t is unsigned long which
can led sparse to emit wrong warnings.

Fix this by passing to sparse the flag -msize-long, telling it
that size_t is unsigned long.
