From 54eb7a55be6779c4d0c25eaf5056498a28595049 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 25 Jun 2022 14:55:56 +0200 Subject: [PATCH] memstick/ms_block: Fix a memory leak 'erased_blocks_bitmap' is never freed. As it is allocated at the same time as 'used_blocks_bitmap', it is likely that it should be freed also at the same time. Add the corresponding bitmap_free() in msb_data_clear().
