From: Colin Ian King <colin.k...@canonical.com>

The array channel_all can be make static const rather than populating
it on the stack, this makes the code smaller.  Also, variable place
is being initialized with a value that is never read, so this assignment
is redundant and can be removed.

Before:
   text    data     bss     dec     hex filename
 118537    9591       0  128128   1f480 realtek/rtlwifi/rtl8821ae/phy.o

After:
   text    data     bss     dec     hex filename
 118331    9687       0  128018   1f412 realtek/rtlwifi/rtl8821ae/phy.o

Saves 110 bytes, (gcc version 9.2.1, amd64)
