Subject: ath9k: Only remove spectral scan relay file when it was created
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=00b54182344ea2ca3e570fd8d9803f8e7dc98fb4;p=linux-beck.git

ath9k: Only remove spectral scan relay file when it was created

The relay file depends on relayfs. Trying to close this file without having
ATH9K_DEBUGFS (and therefore RELAY) activated causes build failures.
