From fa3b38d4c432745b05e417c750c1c59c347fc18e Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 2 Jan 2023 18:21:14 +0100 Subject: [PATCH] cmd: fix return code of 'sf write' and 'sf read' If the offset or the size passed to the 'sf write' or 'sf read' command exceeds the size of the SPI flash displaying the command usage is not helpful. Return CMD_RET_FAILURE instead of CMD_RET_USAGE. Use the CMD_RET_* constants instead of 0, 1, -1. Simplify a logical expression in the final return statement.
