I'm unable to reproduce this on x86 build. I guess <linux/err.h> gets
included implicitly there.

Patch below should fix this. Anton, care to pick this one as well (or fold
it into the 34298d40e585 ("smb347-charger: Convert to regmap API") commit)?

Subject: [PATCH] smb347-charger: include missing <linux/err.h>

Without the include we get build errors like:

drivers/power/smb347-charger.c: In function 'smb347_probe':
drivers/power/smb347-charger.c:1039:2: error: implicit declaration of function 'IS_ERR' [-Werror=implicit-function-declaration]
drivers/power/smb347-charger.c:1040:3: error: implicit declaration of function 'PTR_ERR' [-Werror=implicit-function-declaration]
