-Subject: media: Staging: media: Release the correct resource in an error
- handling path
-
-From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
-
-[ Upstream commit 3b6471c7becd06325eb5e701cc2602b2edbbc7b6 ]
-
-'res' is reassigned several times in the function and if we 'goto
-error_unmap', its value is not the returned value of 'request_mem_region()'
-anymore.
-
-Introduce a new 'struct resource *' variable (i.e. res2) to keep a pointer
-to the right resource, if needed in the error handling path.
-
-Fixes: 4b4eda001704 ("Staging: media: Unmap and release region obtained by ioremap_nocache")
