Message-ID: <20241205070426.1861048-1-psiddaiah@mvista.com> Date: Thu, 5 Dec 2024 12:34:26 +0530 From: psiddaiah@...sta.com To: broonie@...nel.org Cc: linux-spi@...r.kernel.org, linux-kernel@...r.kernel.org, cminyard@...sta.com, Purushothama Siddaiah <psiddaiah@...sta.com> Subject: [PATCH] spi: omap2-mcspi: Fix the IS_ERR() bug for devm_clk_get_optional_enabled() From: Purushothama Siddaiah <psiddaiah@...sta.com> 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.
