RAS: Avoid build errors when CONFIG_DEBUG_FS=n
A new helper was introduced for RAS modules to be able to get the RAS subsystem debugfs root directory. The helper is defined in debugfs.c which is only built when CONFIG_DEBUG_FS=y. However, it's possible that the modules would include debugfs support for optional functionality. One current example is the fmpm module. In this case, a build error will occur when CONFIG_RAS_FMPM is selected and CONFIG_DEBUG_FS=n. Add an inline helper function stub for the CONFIG_DEBUG_FS=n case as the fmpm module can function without the debugfs functionality too. Fixes: 9d2b6fa09d15 ("RAS: Export helper to get ras_debugfs_dir") Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218640 Reported-by: anthony s. knowles <akira.2020@protonmail.com> Signed-off-by: Yazen Ghannam <yazen.ghannam@amd.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Tested-by: anthony s. knowles <akira.2020@protonmail.com> Link: https://lore.kernel.org/r/20240325183755.776-1-bp@alien8.de
