[PATCH 01/13] drm/tegra: dc: Move register definitions into a table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

From: Thierry Reding <treding@xxxxxxxxxx>

After commit 67e04d1ab19b ("drm/tegra: dc: Trace register accesses"),
the debugfs register dump implementation causes excessive stack usage
and can result in build warnings. To fix this, move the register
definitions into a table and iterate over the table while dumping the
registers to debugfs.
