Hi Michael,

Thanks for the quick fix!

We also use name in a couple other places:

1. spi_nor_get_flash_info() prints jinfo->name and info->name() in the
   dev_warn() call.

2. spi_nor_params_show() prints nor->info->name for the debugfs entry.

Since both of these are prints, it should probably be fine since they
should be converted to "(null)" instead. Still, something we should fix.
I don't think those are critical so those can be fixed as follow up
patches. I unfortunately am swamped and don't have the time to fix them
right now.

I also did a quick check to make sure we don't have other flashes
without a name.
