clk: st: Fix memory leak in st_of_quadfs_setup()

2022-12-31T12:14:43+00:00

[ Upstream commit cfd3ffb36f0d566846163118651d868e607300ba ] If st_clk_register_quadfs_pll() fails, @lock should be freed before goto @err_exit, otherwise will cause meory leak issue, fix it.

clk: st: clkgen-fsyn: embed soc clock outputs within compatible data

2021-06-28T02:53:40+00:00

In order to avoid relying on the old style description via the DT clock-output-names, add compatible data describing the flexgen outputs clocks for all STiH407/STiH410 and STiH418 SOCs. In order to ease transition between the two methods, this commit introduce the new compatible without removing the old method. Once DTs will be fixed, the method relying on DT clock-output-names will be removed from this driver as well as old compatibles.

ODF field within the struct clkgen_pll is never used by the driver and can thus be removed. Signed-off-by: Alain Volmat Reviewed-by: Patrice Chotard Link: https://lore.kernel.org/r/20210331201632.24530-2-avolmat@me.com Signed-off-by: Stephen Boyd

clk: st: Remove uninitialized_var() usage

2020-07-16T19:32:25+00:00

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. As a precursor to removing[2] this[3] macro[4], just remove this variable since it was actually unused: drivers/clk/st/clkgen-fsyn.c: In function ‘quadfs_set_rate’: drivers/clk/st/clkgen-fsyn.c:793:6: warning: unused variable ‘i’ [-Wunused-variable] 793 | int i; | ^ [1] https://lore.kernel.org/lkml/20200603174714.192027-1-glider@google.com/ [2] https://lore.kernel.org/lkml/CA+55aFw+Vbj0i=1TGqCR5vQkCzWJ0QxK6CernOU6eedsudAixw@mail.gmail.com/ [3] https://lore.kernel.org/lkml/CA+55aFwgbgqhbp1fkxvRKEpzyR5J8n1vKT1VZdz9knmPuXhOeg@mail.gmail.com/ [4] https://lore.kernel.org/lkml/CA+55aFz2500WfbKXAx8s67wrm9=yVJu65TpLgN_ybYNv0VEOKA@mail.gmail.com/ Fixes: 5f7aa9071e93 ("clk: st: Support for QUADFS inside ClockGenB/C/D/E/F") Acked-by: Stephen Boyd Signed-off-by: Kees Cook
