Subject: [PATCH] srcu: fix kernel-doc missing notation

From: Randy Dunlap <rdunlap@...radead.org>

Fix kernel-doc warnings for missing parameter descriptions:

../include/linux/srcu.h:175: warning: Function parameter or member 'p' not described in 'srcu_dereference_notrace'
../include/linux/srcu.h:175: warning: Function parameter or member 'sp' not described in 'srcu_dereference_notrace'

Fixes: 0b764a6e4e19d ("srcu: Add notrace variant of srcu_dereference")
