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

[ Upstream commit 4c6ac5446d060f0bf435ccc8bc3aa7b7b5f718ad ]
The devm_clk_get_optional_enabled() function returns error pointers(PTR_ERR()). So use IS_ERR() to check it.
Verified on K3-J7200 EVM board, without clock node mentioned in the device tree.
