Subject: mm: fix up sparse warning in gfpflags_allow_blocking
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=21fa8442799945beaca074cb5bcf7cfe24969d59;p=openwrt%2Fstaging%2Fblogic.git

mm: fix up sparse warning in gfpflags_allow_blocking

sparse says:

    include/linux/gfp.h:274:26: warning: incorrect type in return expression (different base types)
    include/linux/gfp.h:274:26:    expected bool
    include/linux/gfp.h:274:26:    got restricted gfp_t

...add a forced cast to silence the warning.
