Subject: be2net: move async cmd processing to a separate routine
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=559b633f426dabed1e4ab91c41b7bf8ff2b07367;p=linux-beck.git

be2net: move async cmd processing to a separate routine

For some FW cmds, the caller just issues the cmd and doesn't wait for a
response. The response handling is done in the MCCQ compl processing context
only. Move this code into a separate routine to make be_mcc_compl_process()
more manageable.
