2022-12-31clk: st: Fix memory leak in st_of_quadfs_setup()Xiu Jianfeng1-2/+3
[ 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.

2022-01-06clk: st: clkgen-fsyn: search reg within node or parentAlain Volmat1-2/+11
In order to avoid having duplicated addresses within the DT, only have one unit-address per clockgen and each driver within the clockgen should look at the parent node (overall clockgen) to figure out the reg property. Such behavior is already in place in other STi platform clock drivers such as clk-flexgen and clkgen-pll. Keep backward compatibility by first looking at reg within the node before looking into the parent node.

2021-06-28clk: st: clkgen-fsyn: embed soc clock outputs within compatible dataAlain Volmat1-12/+101
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.

2020-07-16clk: st: Remove uninitialized_var() usageKees Cook1-1/+0
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 <sboyd@kernel.org> Signed-off-by: Kees Cook <keescook@chromium.org>

2018-06-13treewide: kzalloc() -> kcalloc()Kees Cook1-1/+1
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;
