[ Upstream commit 1435e895d4fc967d64e9f5bf81e992ac32f5ac76 ]

Add error handling to propagate amdgpu_cgs_create_device() failures
to the caller. When amdgpu_cgs_create_device() fails, release hwmgr
and return -ENOMEM to prevent null pointer dereference.

[v1]-&gt;[v2]: Change error code from -EINVAL to -ENOMEM. Free hwmgr.

<content type='text'>
commit d9d4cb224e4140f51847642aa5a4a5c3eb998af0 upstream.

Currently, it seems like the code was carried over from RDNA3 because
it assumes two possible values to set. RDNA4, instead of having:
0: min SCLK
1: max SCLK
only has
0: SCLK offset

This change makes it so it only reports current offset value instead of
showing possible min/max values and their indices. Moreover, it now only
accepts the offset as a value, without the indice index.

Additionally, the lower bound was printed as %u by mistake.

Old:
OD_SCLK_OFFSET:
0: -500Mhz
1: 1000Mhz

0: 97Mhz
1: 1259MHz
OD_VDDGFX_OFFSET:

MCLK:      97Mhz       1500Mhz

MCLK:      97Mhz       1500Mhz

Setting this offset:
Old: "s 1 &lt;offset&gt;"

[ Upstream commit 357445e28ff004d7f10967aa93ddb4bffa5c3688 ]

The function atomctrl_get_smc_sclk_range_table() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to
retrieve SMU_Info table, it returns NULL which is later dereferenced.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

In practice this should never happen as this code only gets called
on polaris chips and the vbios data table will always be present on
those chips.

Fixes: a23eefa2f461 ("drm/amd/powerplay: enable dpm for baffin.")
