base: phandle_safe_name: replace all invalid label characters#766
Merged
Conversation
DTS labels must be valid C identifiers ([a-zA-Z_][a-zA-Z0-9_]*), but node names can contain characters from the set [0-9a-zA-Z,._+-]. Previously, phandle_safe_name() only replaced '@', '-', and '/'. This left ',' , '.' and '+' in the generated label, producing invalid DTS output (e.g., "pcie0,0:" for node pcie@0,0). Add replacements for ',', '.', and '+' so that all non-identifier characters in node names are converted to '_'. Signed-off-by: Raju Kumar Pothuraju <rajukumar.pothuraju@amd.com>
