Subject: trace: cma: remove unnecessary event class cma_alloc_class
Date: Thu, 23 Mar 2023 19:41:36 +0800
After commit cb6c33d4dc09 ("cma: tracing: print alloc result in
trace_cma_alloc_finish"), cma_alloc_class has only one event which is
cma_alloc_busy_retry. So we can remove the cma_alloc_class.
