Subject: cg3: add explicit ram_addr_t cast to scanline page variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8eb57ae3f9afdd8d911f3b2862e05cd0bb042b4e;p=qemu.git

cg3: add explicit ram_addr_t cast to scanline page variable

Coverity warns that multiplying two 32-bit values gives a 32-bit result which
is assigned to a 64-bit variable. Add an explicit ram_addr_t cast to silence
the warning.
