Message-id: <1431500087-2275-1-git-send-email-k.kozlowski@samsung.com> Date: Wed, 13 May 2015 15:54:39 +0900 From: Krzysztof Kozlowski <k.kozlowski@...sung.com> To: Tero Kristo <t-kristo@...com>, Mike Turquette <mturquette@...aro.org>, Stephen Boyd <sboyd@...eaurora.org>, linux-omap@...r.kernel.org, linux-clk@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Krzysztof Kozlowski <k.kozlowski@...sung.com> Subject: [RFT PATCH 0/8] clk: ti: Fix possible ERR_PTR dereferences from clk_get_sys Hi, clk_get_sys() may return ERR_PTR but the drivers immediately dereferenced the return value. This could lead to oops. I tried only to fix possible ERR_PTR dereference and to not change the logic. This is why some of the patches look quite complex. For example in clk-7xx driver proceeds to next clocks if first one fails. WARNING: The patchset was only compile tested (plus static checkers), as I do not have the hardware. I am kindly asking for tests.
