If anyone has any objections, please let me know. ------------------ From: Sergei Shtylyov [ Upstream commit c81400be716aa4c76f6ebf339ba94358dbbf6da6 ] When unloading the driver that drives an EISA board, a message similar to the following one is displayed: Trying to free nonexistent resource <0000000000013000-000000000001301f> Then an user is unable to reload the driver because the resource it requested in the previous load hasn't been freed. This happens most probably due to a typo in vortex_eisa_remove() which calls release_region() with 'dev->base_addr' instead of 'edev->base_addr'...
