From 0d1ecc99cb59c2190257f7738f91db21f174dc02 Mon Sep 17 00:00:00 2001 From: Marek Behún Date: Tue, 5 Oct 2021 15:56:06 +0200 Subject: mtd: Remove mtd_erase_callback() entirely MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The original purpose of mtd_erase_callback() in Linux at the time it was imported to U-Boot, was to inform the caller that erasing is done (since it was an asynchronous operation). All supplied callback methods in U-Boot do nothing, but the mtd_erase_callback() function was (until previous patch) grossly abused in U-Boot's mtdpart implementation for completely different purpose. Since we got rid of the abusement, remove the mtd_erase_callback() function and the .callback member from struct erase_info entirely, in order to avoid such problems in the future.
