UBIFS: endian handling fixes and annotations
Noticed by sparse:
fs/ubifs/file.c:75:2: warning: restricted __le64 degrades to integer
fs/ubifs/file.c:629:4: warning: restricted __le64 degrades to integer
fs/ubifs/dir.c:431:3: warning: restricted __le64 degrades to integer
This should be checked to ensure the ubifs_assert is working as
intended, I've done the suggested annotation in this patch.
fs/ubifs/sb.c:298:6: warning: incorrect type in assignment (different base types)
fs/ubifs/sb.c:298:6: expected int [signed] [assigned] tmp
fs/ubifs/sb.c:298:6: got restricted __le64 [usertype] <noident>

fs/ubifs/sb.c:300:19: got int [signed] [assigned] tmp
fs/ubifs/sb.c:301:19: warning: incorrect type in assignment (different base types)
fs/ubifs/sb.c:301:19: expected restricted __le64 [usertype] mtime_sec
fs/ubifs/sb.c:301:19: got int [signed] [assigned] tmp
This looks like a bugfix as your tmp was a u32 so there was truncation in
the atime, mtime, ctime value, probably not intentional, add a tmp_le64
and use it here.
fs/ubifs/key.h:348:9: warning: cast to restricted __le32
fs/ubifs/key.h:348:9: warning: cast to restricted __le32
fs/ubifs/key.h:419:9: warning: cast to restricted __le32
Read from the annotated union member instead.
fs/ubifs/recovery.c:175:13: warning: incorrect type in assignment (different base types)
fs/ubifs/recovery.c:175:13: expected unsigned int [unsigned] [usertype] save_flags
fs/ubifs/recovery.c:175:13: got restricted __le32 [usertype] flags
fs/ubifs/recovery.c:186:13: warning: incorrect type in assignment (different base types)
fs/ubifs/recovery.c:186:13: expected restricted __le32 [usertype] flags
fs/ubifs/recovery.c:186:13: got unsigned int [unsigned] [usertype] save_flags
Do byteshifting at compile time of the flag value. Annotate the saved_flags
as le32.
fs/ubifs/debug.c:368:10: warning: cast to restricted __le32
fs/ubifs/debug.c:368:10: warning: cast from restricted __le64
Should be checked if the truncation was intentional, I've changed the
printk to print the full width.
