This 2 patch series provides fixes to ETF null pointer dereference crash
and TRCVMIDCCTLR1 register save and restore fix.

Patch 1 is an RFC since I am not sure of the fix provided since it looks
more like a band-aid than the actual fix.

Changes in v2:
 * Remove extra fixes tag (Suzuki)

Sai Prakash Ranjan (2):
  coresight: tmc-etf: Fix NULL pointer dereference in
    tmc_enable_etf_sink_perf()
  coresight: etm4x: Fix save and restore of TRCVMIDCCTLR1 register
