[PATCH 6.6 021/331] wifi: iwlwifi: uninitialized variable in iwl_acpi_get_ppag_table()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit 65c6ee90455053cfd3067c17aaa4a42b0c766543 ]

This is an error path and Smatch complains that "tbl_rev" is uninitialized
on this path.  All the other functions follow this same patter where they
set the error code and goto out_free so that's probably what was intended
here as well.
