treewide: refresh kmalloc_obj() conversionsgrafted
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

+ * @max_channels_clocked: Maximum number of channels that I2S clocks will be
+ * generated for. Useful when clock master for systems
+ * where the I2S bus has multiple data lines.
+ * @dmic_ref: Indicates how the MICBIAS pins have been externally
+ * connected to DMICs on each input. A value of 0
+ * indicates MICVDD and is the default. Other values are:
+ * For CS47L35 one of the CS47L35_DMIC_REF_xxx values
+ * For all other codecs one of the MADERA_DMIC_REF_xxx
+ * Also see the datasheet for a description of the
+ * INn_DMIC_SUP field.
+ * @inmode: Mode for the ADC inputs. One of the MADERA_INMODE_xxx
+ * values. Two-dimensional array
+ * [input_number][channel number], with four slots per
+ * input in the order
+ * [n][0]=INnAL [n][1]=INnAR [n][2]=INnBL [n][3]=INnBR
+ * @out_mono: For each output set the value to TRUE to indicate that
+ * the output is mono. [0]=OUT1, [1]=OUT2, ...
+ * @pdm_fmt: PDM speaker data format. See the PDM_SPKn_FMT field in
+ * the datasheet for a description of this value.
+ * @pdm_mute: PDM mute format. See the PDM_SPKn_CTRL_1 register
+ * in the datasheet for a description of this value.
