Subject: RISC-V: ACPI: Update the return value of acpi_get_rhct()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a06835227280436c1aae021a3f43d3abfcba3835;p=linux.git

RISC-V: ACPI: Update the return value of acpi_get_rhct()

acpi_get_rhct() currently returns pointer to acpi_table_header
structure. But since this is specific to RHCT, return pointer to
acpi_table_rhct structure itself.
