From d9ee6015e573176e599693b6d0125ad74b210623 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 18 Aug 2017 11:05:19 +0300 Subject: [PATCH] rtlwifi: make a couple arrays larger This is a static checker fix. "cal_num" is 10. We're declaring the tx_dt[] and rx_td[] arrays as 3 element arrays. The static checker complains that we do: tx_dt[cal] = (vdf_y[1]>>20)-(vdf_y[0]>>20); "cal" is the iterator and it is in the 0-9 range so it looks like we could corrupt memory.
