Commit Message

Laurent Pinchart April 21, 2022, 11:42 p.m. UTC 
To avoid cluttering the main rkisp1-dev.c driver file, move debugfs code
to a separate source file. This prepares for extensions to the debugfs
infrastructure.

While at it, add a missing forward declaration for struct dentry in
rkisp1-common.h to avoid depending on indirect includes.
