Subject: ath10k: spectral: remove redundant check in write_file_spectral_count()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d83c0d3293bbf3fe40ce9e1ac273309a44bbde91;p=linux.git

ath10k: spectral: remove redundant check in write_file_spectral_count()

Variable val is unsigned, so checking whether it is less than zero is
redundant.
