media: cec: core: avoid recursive cec_claim_log_addrs
Keep track if cec_claim_log_addrs() is running, and return -EBUSY if it is when calling CEC_ADAP_S_LOG_ADDRS. This prevents a case where cec_claim_log_addrs() could be called while it was still in progress. Signed-off-by:Hans Verkuil <hverkuil-cisco@xs4all.nl> Reported-by:
