[ Upstream commit b8bea8a5e5d942e62203416ab41edecaed4fda02 ] Because CONFIG_OF defined for MIPS, cacheinfo attempts to fill information from DT, ignoring data filled by architecture routine. This leads to error reported cacheinfo: Unable to detect cache hierarchy for CPU 0 Way to fix this provided in commit fac51482577d ("drivers: base: cacheinfo: fix x86 with CONFIG_OF enabled") Utilize same mechanism to report that cacheinfo set by architecture specific function Signed-off-by: Vladimir Kondratiev <vladimir.kondratiev@linux.intel.com> Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: James Hogan <jhogan@kernel.org> Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Sasha Levin <sashal@kernel.org> --- arch/mips/kernel/cacheinfo.c | 2 ++ 1 file changed, 2 insertions(+)
