[PATCH] staging: fbtft: add typecast in call to vfree()

[Lars Svensson]

Member screen_base in struct fb_info is declared __iomem causing
a sparse warning as below when passed to vfree(). This adds typecast
(__force void *) to silence the warning.

fbtft-core.c:922:39: warning: incorrect type in argument 1 \
(different address spaces)
fbtft-core.c:922:39:    expected void const *addr
fbtft-core.c:922:39:    got char [noderef] <asn:2>*screen_base
