From 87386ee83dc2b241eab69239f9cc82fa7fb4171c Mon Sep 17 00:00:00 2001 From: Jay Lu Date: Tue, 6 Dec 2022 14:52:33 -0600 Subject: ACPI: APEI: EINJ: Refactor available_error_type_show() Move error type descriptions into an array and loop over error types to improve readability and maintainability. Replace seq_printf() with seq_puts() as recommended by checkpatch.pl. Signed-off-by: Jay Lu Co-developed-by: Ben Cheatham Signed-off-by: Ben Cheatham Reviewed-by: Tony Luck Signed-off-by: Rafael J.
