staging: erofs: fix potential overflow in z_erofs_vle_normalaccess_readpage{,s}
As Dan reported in the LKP mailing list:
https://lists.01.org/pipermail/kbuild-all/2018-August/051558.html
New smatch warnings:
drivers/staging/erofs/unzip_vle.c:1359 z_erofs_vle_normalaccess_readpages() warn: should '()->index << 12' be a 64 bit type?
Old smatch warnings:
drivers/staging/erofs/unzip_vle.c:1322 z_erofs_vle_normalaccess_readpage() warn: should 'page->index << 12' be a 64 bit type?
It needs to cast variable's type to erofs_off_t before left shifting.
