Subject: [PATCH] drm/vc4: hdmi: Deal with multiple debugfs files
|
||
|
|
|
||
|
|
The HDMI driver was registering a single debugfs file so far with the name
|
||
|
|
hdmi_regs.
|
||
|
|
|
||
|
|
Obviously, this is not going to work anymore when will have multiple HDMI
|
||
|
|
controllers since we will end up trying to register two files with the same
|
||
|
|
name.
|
||
|
|
|
||
|
|
Let's use the ID to avoid that name conflict.
