On my embedded system I use this tpm infineon chip via i2c bus. The system is a MIPS architecture and therefore works in big endian mode. The problem is, that the chip type is not correctly recognized, because the vendor ID is wrongly aligned in the memory. By declaring the vendor ID variable as a `__le32` type, the TPM chip is then correctly recognized by the driver and feels then responsible.
Please no hyphens just normal single quotes. You should have always in a commit message some explanation what the patch does in imperative form, e.g. "Change type of xxx ... because ...". I cannot from find a variable named "vendor ID" from tpm_tis_i2c_init(). Maybe you are referring to the variable, of which name is "vendor"? Finally, the commit message lacks explanation what is changed, i.e. tpm2_tis_i2c_init() in this case. Did you find the commit ID where this regression was introduceD? /Jarkko
