From e4f4ffa8a98c24a4ab482669b1e2b4cfce3f52f4 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 18 May 2020 11:10:43 -0700 Subject: input: i8042 - Remove special PowerPC handling This causes a build error with CONFIG_WALNUT because kb_cs and kb_data were removed in commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and include/asm-ppc"). ld.lld: error: undefined symbol: kb_cs > referenced by i8042-ppcio.h:28 (drivers/input/serio/i8042-ppcio.h:28) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a > referenced by i8042-ppcio.h:28 (drivers/input/serio/i8042-ppcio.h:28) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a > referenced by i8042-ppcio.h:28 (drivers/input/serio/i8042-ppcio.h:28) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a ld.lld: error: undefined symbol: kb_data > referenced by i8042.c:309 (drivers/input/serio/i8042.c:309) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a > referenced by i8042-ppcio.h:33 (drivers/input/serio/i8042-ppcio.h:33) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a > referenced by i8042.c:319 (drivers/input/serio/i8042.c:319) > input/serio/i8042.o:(__i8042_command) in archive drivers/built-in.a > referenced 15 more times Presumably since nobody has noticed this for the last 12 years, there is not anyone actually trying to use this driver so we can just remove this special walnut code and use the generic header so it builds for all configurations.
