rtlwifi: rtl8821ae: make array static const and remove redundant assignment
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) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
