Subject: [PATCH 1/1 linux-next] udf: use int for allocated blocks instead of sector_t

Fix the following warnings:

fs/udf/balloc.c:768:15: warning: conversion to 'sector_t' from 'int'
may change the sign of the result [-Wsign-conversion]
   allocated = udf_bitmap_prealloc_blocks(sb,

   allocated = udf_table_prealloc_blocks(sb,
               ^
fs/udf/balloc.c:778:15: warning: conversion to 'sector_t' from 'int'

   inode_add_bytes(inode, allocated << sb->s_blocksize_bits);
                          ^
fs/udf/balloc.c:792:2: warning: conversion to 'int' from 'sector_t'
