>          * Fix link issue with patch v2 08/10 "Split tpm_i2c_tpm_st33 in 2 layers (core + phy)" when building as a module.
>          The symbols wasn't exported in st33zp24.c.
>          * Add missing MODULE_LICENSE in patch v2 09/10 "Add st33zp24 spi phy"
>          * Fix node example in dts spi documentation in patch v2 10/10 "Add dts documentation for st33zp24 spi phy"
>          * Fix typo on Jason Gunthorpe first name. Sorry for that :(...
>          * Change contact email address as tpmsupport-qxv4g6HH51o@public.gmane.org is no more valid
> - v4 adds missing module_license in st33zp24
> - v5 includes as best as possible PeterHuewe comments.
> - v6 is more explicit about the spi buffer size and remove their buffer (tx_buf/rx_buf) dynamic allocation
> - v7 fix scripts/checkpatch.pl error
