These patches silence some mt762x PCIe driver error messeges by removing
the useless debugging codes and replacing incorrectly used 'dev_err()'
with 'dev_info()':
PCI: mt7621: Use dev_info() to log PCIe card detection [1]
mips: pci-mt7620: do not print NFTS register value as error log [2]
mips: pci-mt7620: use dev_info() to log PCIe device detection result [3]
Patch [1] has already been merged into the Linux 6.3 branch. Patches [2] and
[3] have been merged into the "mips-next" tree, and they will be part of the
upcoming Linux 6.5.

Subject: [PATCH 2/2] mips: pci-mt7620: use dev_info() to log PCIe device
|
|
detection result
|
|
|
|
Usually, We only need to print the error log when there is a PCIe card but
|
|
initialization fails. Whether the driver finds the PCIe card or not is the
|
|
expected behavior. So it's better to log these information with dev_info().
|
|
|
|
Tested on MT7628AN router Motorola MWR03.
