Subject: ath10k: add might_sleep() to ath10k_wmi_cmd_send()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=56b84287d14aa74823a9c290d0c5839d38365110;p=openwrt%2Fstaging%2Fblogic.git

ath10k: add might_sleep() to ath10k_wmi_cmd_send()

ath10k_wmi_cmd_send() will now sleep if there are no credits available.
To make it easier to catch callers in atomic context add might_sleep()
to the function.
