Hello Stan,
Greg has the same issue with patching the kernel 5.13 [1]. We have to
wait for a solution.

The patch below does not apply to the 5.13-stable tree.
If someone wants it applied there, or to any other stable or longterm
tree, then please email the backport, including the original git commit
id to <stable at vger.kernel.org>.
thanks,

Subject: [PATCH] drm/radeon/ni_dpm: Fix booting bug
Create new structure NISLANDS_SMC_SWSTATE_SINGLE, as initialState.levels
and ACPIState.levels are never actually used as flexible arrays. Those
arrays can be used as simple objects of type
NISLANDS_SMC_HW_PERFORMANCE_LEVEL, instead.
Currently, the code fails because flexible array _levels_ in
struct NISLANDS_SMC_SWSTATE doesn't allow for code that access
the first element of initialState.levels and ACPIState.levels
arrays:
drivers/gpu/drm/radeon/ni_dpm.c:
1690 table->initialState.levels[0].mclk.vMPLL_AD_FUNC_CNTL =
1691 cpu_to_be32(ni_pi->clock_registers.mpll_ad_func_cntl);
...
1903: table->ACPIState.levels[0].mclk.vMPLL_AD_FUNC_CNTL =
cpu_to_be32(mpll_ad_func_cntl);
1904: table->ACPIState.levels[0].mclk.vMPLL_AD_FUNC_CNTL_2 =
cpu_to_be32(mpll_ad_func_cntl_2);
because such element cannot exist without previously allocating
any dynamic memory for it (which never actually happens).
That's why struct NISLANDS_SMC_SWSTATE should only be used as type
for object driverState and new struct SISLANDS_SMC_SWSTATE_SINGLE is
created as type for objects initialState, ACPIState and ULVState.
Also, with the change from one-element array to flexible-array member
in commit 434fb1e7444a ("drm/radeon/nislands_smc.h: Replace one-element
array with flexible-array member in struct NISLANDS_SMC_SWSTATE"), the
size of dpmLevels in struct NISLANDS_SMC_STATETABLE should be fixed to
be NISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE instead of
NISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE - 1.

array with flexible-array member in struct NISLANDS_SMC_SWSTATE")
