[ Upstream commit 7359608a271ce81803de148befefd309baf88c76 ]
Commit ed66f991bb19 ("module: Refactor section attr into bin attribute") removed the 'name' field from 'struct module_sect_attr' triggering the following error when invoking lx-symbols:
Has ed66f991bb19 ("module: Refactor section attr into bin attribute") been backported to 4.19? It doesn't /sound/ like something that would require backporting unless something else depended up on it, but if it hasn't been ... then *this* patch shouldn't be either...
Same for 5.4, and 5.7 that's just come in.
This patch will 'apply' cleanly, and not hit any compilation errors, as it only changes python code... so my reason to highlight is in case some automated system picked it up based on those assumptions.
If ed66f991bb19 has also been backported, then I'm sorry for the noise ;-)

This patch fixes the issue taking the module name from the 'struct attribute'.
