[PATCH AUTOSEL 5.7 021/274] net: ethernet: ti: fix return value check in k3_cppi_desc_pool_create_name()

[Sasha Levin]

From: Wei Yongjun <weiyongj...@huawei.com>

[ Upstream commit 2ac757e4152e3322a04a6dfb3d1fa010d3521abf ]

In case of error, the function gen_pool_create() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: 93a76530316a ("net: ethernet: ti: introduce am65x/j721e gigabit eth 
subsystem driver")
