From 125b28b18926e050e770160a5897b81082304f8c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 15 Feb 2024 13:16:03 +0000 Subject: spi: dw: remove redundant assignment to variable len The variable id len being initialized with a value that is never read, it is being re-assigned later on in a for-loop. The initialization is redundant and can be removed.
