[PATCH 03/10] staging: rtl8192e: Remove unused variable rxSNRdB

From: Philipp Hortmann
Date: Sun Jan 29 2023 - 09:58:46 EST


rxSNRdB is initialized and set but never read. Remove dead code. Local
variable rx_snrX is then of no use. Remove rx_snrX as well. Local
variable tmp_rxsnr is then of no use. Remove tmp_rxsnr as well.
