Browse Source 
Build warnings exist on a gcc based 16 bit compiler. Cast relevant types
to fix.

littlefs/lfs.c: In function 'lfs_gstate_xororphans':
littlefs/lfs.c:355:5: warning: left shift count >= width of type
littlefs/lfs.c: In function 'lfs_dir_fetchmatch':
littlefs/lfs.c:849:17: warning: left shift count >= width of type
littlefs/lfs.c: In function 'lfs_dir_commitcrc':
littlefs/lfs.c:1278:9: warning: left shift count >= width of type
