[PATCH][next] rtlwifi: rtl8192de: Fix uninitialized variable place

STALE1863d

From: Colin King <hidden>
Date: 2021-08-29 18:05:14
Also in: kernel-janitors, linux-wireless, lkml
Subsystem: realtek wireless driver (rtlwifi family), the rest · Maintainers: Ping-Ke Shih, Linus Torvalds

From: Colin Ian King <redacted>

In the case where chnl <= 14 variable place is not initialized and
the function returns an uninitialized value. This fixes an earlier
cleanup where I introduced this bug. My bad.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 369956ae5720 ("rtlwifi: rtl8192de: Remove redundant variable initializations")
