Subject: [PATCH] TPM: Fix compiler warnings
|
||
|
|
|
||
|
|
Stop defining our own Event type in tpm.c instead use the one from
|
||
|
|
the header, so that it matches the function prototype.
|
||
|
|
Note this requires some further code changes to go from all lowercaps
|
||
|
|
of the private Event type to the CamelCaps from the header.
|
||
|
|
|
||
|
|
Also cast buf, which gets passed as a efi_physicall_address_t to an
|
||
|
|
integer, to avoid the compiler complaining about passing a pointer as
|
||
|
|
an integer.
|
||
|
|
