From: Purushothama Siddaiah <psiddaiah@xxxxxxxxxx> [ 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.
