Subject: ath10k: remove redundant check of len with buf_len
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eed4721fb6172b3051a8341f9089b728681a9454;p=openwrt%2Fstaging%2Fblogic.git

ath10k: remove redundant check of len with buf_len

The check of len > buf_len is redundant as len is initialized
to 0 and buf_len to 4096, so this comparison is always false.
Remove it.
