Subject: [PATCH] memstick/ms_block: Fix a memory leak
Git-commit: 54eb7a55be6779c4d0c25eaf5056498a28595049
Patch-mainline: v6.0-rc1
References: git-fixes

'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().

Fixes: 0ab30494bc4f ("memstick: add support for legacy memorysticks")
