Subject: [PATCH -mm] drivers/acpi/tables/tbutils.c: Shut up bogus uninitialized
 variable warning


drivers/acpi/tables/tbutils.c: In function 'acpi_tb_parse_root_table':
drivers/acpi/tables/tbutils.c:403:
warning: 'rsdt_address' may be used uninitialized in this function

has been verified to be a bogus warning. Let's just initialize the
variable to zero and shut this up.

Signed-off-by: Satyam Sharma <satyam@...radead.org>

---

I didn't use uninitialized_var() here because drivers/acpi/ is dual-licensed
stuff and used elsewhere, where that macro may be unavailable (?)
