> This is caused by dereferencing 'rpmb' after put_device(). I suggest to improve also this change description. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=051143e1602d90ea71887d92363edd539d411de5#n151 How do you think about a wording variant like the following? The data structure member “rpmb->md” was passed to a call of the function “mmc_blk_put” after a call of the function “put_device”. Reorder these function calls to keep the data accesses consistent. Would you like to add the tag “Fixes” to the commit message? Regards, Markus
