In the Linux kernel, the following vulnerability has been resolved:

i2c: mlxbf: Fix use-after-free in mlxbf_i2c_init_resource()

If devm_platform_get_and_ioremap_resource() returns an error,
mlxbf_i2c_init_resource() frees tmp_res before reading tmp_res->io to
get the error code. This results in a use-after-free.

Save the error code before freeing tmp_res.
