Hi Jarkko,
[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]
reproduce: # apt-get install sparse make ARCH=x86_64 allmodconfig make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
>> drivers/char/tpm/tpm_tis.c:136:13: sparse: cast to restricted __le32
