From f668027521561d1071ccf54500c82a58a1918b2b Mon Sep 17 00:00:00 2001 From: Russell Currey Date: Mon, 24 Oct 2022 15:13:46 +1100 Subject: [PATCH] powerpc/8xx: Fix warning in hw_breakpoint_handler() In hw_breakpoint_handler(), ea is set by wp_get_instr_detail() except for 8xx, leading the variable to be passed uninitialised to wp_check_constraints(). This is safe as wp_check_constraints() returns early without using ea, so just set it to make the compiler happy.
