[PATCH 0/2][SRU][OEM-5.17] Intel iwlwifi AX211: WRT: Failed to set DRAM buffer for alloc id 1, ret=-1

[You-Sheng Yang]

From: "You-Sheng Yang (vicamo)" <vicamo.yang at canonical.com>

[Impact]

Kernel warning dumps at boot on Intel iwlwifi AX211 equipped platforms
running oem-5.17 kernel:

kernel: iwlwifi 0000:00:14.3: WRT: Failed to set DRAM buffer for alloc
id 1, ret=-1
kernel: iwlwifi 0000:00:14.3: WRT: Failed to set DRAM buffer for alloc
id 2, ret=-1
kernel: iwlwifi 0000:00:14.3: WRT: Failed to set DRAM buffer for alloc
id 3, ret=-1

[Fix]

v5.18-rc1 upstream commit c76c83097587 ("iwlwifi: dbg-tlv: clean up
iwl_dbg_tlv_update_drams()" skips unnecessary dumps and therefore avoid
this kernel warning.

Commit ab23da483bd7 is to allocation debug fragments correctly.

[Test Case]

Reboot with prebuilt kernel and it shall no longer warns about it.

[Where problems could occur]

The original patch was meant to avoid allocating a struct iwl_dram_info
on the stack by reusing an existing debug-only fragment, there is no
impact for ordinary driver use.

[Other Info]

While this affects only v5.17 and above, and the fixes are in v5.18-rc1,
it follows oem-5.17 is the only victim here.
