X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=01e0efe3178dbeed1284e55b70a3160a279995b2;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: mvm: fix SRAM dump debugfs handler

If the length isn't set it means we want all the SRAM.
Also - this is perfectly valid to partially dump starting
at offset 0.
