Sashiko AI review found 2 potential issue(= s) to consider: - [Medium] clk: berlin: missing .disable callbacks in sysmgr clock operatio= ns - [Low] kbuild: Linker error due to missing Kconfig dependency for SL261X_P= LL -- commit 56d97606c2f6bbb88d4a36a5f8b06b807c05523d Author: Jisheng Zhang clk: berlin: add Synaptics SL261X SoC clocks and plls Add support for clocks, plls in Synaptics SL261X SoCs. > diff --git a/drivers/clk/berlin/Kconfig b/drivers/clk/berlin/Kconfig > new file mode 100644 > --- /dev/null > +++ b/drivers/clk/berlin/Kconfig [ ... ] > +config SL261X_CLK > + tristate "Synaptics SL261X Clock Driver" > + depends on ARCH_BERLIN || COMPILE_TEST > + select SL_COMMON_CLK > + select SL_SYSMGR_CLK > + default n [Severity: Low] Does this missing dependency lead to a linker error? The SL261X_CLK config fails to declare a dependency or select on SL261X_PLL, but the clock driver unconditionally calls sl261x_pll_register() defined in the PLL driver. If CONFIG_SL261X_CLK=3Dy but CONFIG_SL261X_PLL=3Dn or m, the build will fail w= ith an undefined reference.

The ops struct for gate clocks implements .enable to ungate the clock but omits the .disable callba= ck. When a consumer driver calls clk_disable_unprepare(), the common clock framework will silently skip the hardware operation, leaking power.

The ops stru= ct for divider clocks implements .enable but also omits the .disable callback.

[Severity: Low] This is the call to sl261x_pll_register() mentioned above that requires SL261X_PLL to be selected or depended on in Kconfig to avoid linker errors. --=20 Sashiko AI review =C2=B7 https://sashiko.dev/#/patchset/20260929061417.2073= 3-1-jszhang@kernel.org?part=3D16 From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from bombadil.infradead.org (bombadil.infradead.org [198.137.202.133]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.lore.kernel.org (Postfix) with ESMTPS id CEEA6CA5FA1 for ;
