[Xen-devel] [PATCH for-4.7 3/6] rombios/tcgbios: initialise logdataptr in HashLogEvent32

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Gcc complains:

tcgbios.c: In function ‘HashLogEvent32’:
tcgbios.c:1131:10: error: ‘logdataptr’ may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
    entry = tcpa_extend_acpi_log(logdataptr);

It fails to figure out when logdataptr is used it is always initialised
in a if block a few line above.
