Subject: [PATCH 10/13] UPSTREAM: mwifiex: scan: Simplify code
|
||
|
|
|
||
|
|
This patch:
|
||
|
|
- improves code layout
|
||
|
|
- removes a useless memset(0) for some memory allocated with kzalloc
|
||
|
|
- removes a useless if. We know that 'if (chan_band_tlv)' will succeed
|
||
|
|
because it has been tested a few lines above
