From 81284e86bf8849f8e98e8ead3ff5811926b2107f Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 15 Jul 2025 19:45:23 -0700 Subject: [PATCH] wifi: brcmsmac: Remove const from tbl_ptr parameter in wlc_lcnphy_common_read_table() A new warning in clang [1] complains that diq_start in wlc_lcnphy_tx_iqlo_cal() is passed uninitialized as a const pointer to wlc_lcnphy_common_read_table(): drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_lcn.c:2728:13: error: variable 'diq_start' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 2728 | &diq_start, 1, 16, 69); | ^~~~~~~~~ The table pointer passed to wlc_lcnphy_common_read_table() should not be considered constant, as wlc_phy_read_table() is ultimately going to update it. Remove the const qualifier from the tbl_ptr to clear up the warning.
