During clock registration, the common\nclock framework calls clk_divider_recalc_rate(), which dereferences\nthe address through readl(). As a result, probing an ADE9000 configured\nas a clock provider with an external input clock crashes.\n\nCLKOUT passes CLKIN through without changing its rate. Register it as\na 1:1 fixed-factor clock, which does not require register access.\n\nThis change does not affect the configuration using the internal clock,\nfor which the driver does not register a clock provider.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/134aa31a8d4e71f6ab1d155ad7b4502508832f72","tags":[]},{"url":"https://git.kernel.org/stable/c/49ee1c6a3ebda6b7de06b2961b0e09c1c3fe536a","tags":[]},{"url":"https://git.kernel.org/stable/c/d2400175228fbc10b29c49a7b5f70a7e80d144dd","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
