[PATCH -next] ASoC: rk817: Constify static struct snd_soc_dai_ops
by Wei Yongjun 18 Jun '21

18 Jun '21

The snd_soc_dai_ops structures is only stored in the ops field of a snd_soc_dai_driver structure, so make the snd_soc_dai_ops structure const to allow the compiler to put it in read-only memory.

[PATCH] soundwire: stream: Use polling for DP Prepare completion
by Richard Fitzgerald 18 Jun '21

18 Jun '21

sdw_prep_deprep_slave_ports() cannot use the port interrupt to signal CP_SM completion because it is called while holding the bus lock, which blocks the alert handler from running. Change to polling the PREPARESTATUS register and remove the infrastructure that was implemented for the previous interrupt waiting. A new configuration field 'ch_prep_poll_us' is added to struct sdw_dpn_prop so that the peripheral driver may select a polling interval. If this is left at zero a default interval of 500 usec is used.

[PATCH] ALSA: firewire-motu: fix rx packet format at higher rate for MOTU 828 mk3 Hybrid
by Takashi Sakamoto 18 Jun '21

18 Jun '21

I assumed that the combination of packet formats for MOTU 828 mk3 Hybrid is the same as MOTU 828 mk3 FireWire. However at higher sampling rate, it is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for rx packet. This commit fixes the issue to which I address at a commit f2ac3b839540 ("ALSA: firewire-motu: sequence replay for source packet header").

[bug report] ASoC: codecs: wcd938x: add capture dapm widgets

Hello Srinivas Kandagatla, The patch d5add08fcbce: "ASoC: codecs: wcd938x: add capture dapm widgets" from Jun 9, 2021, leads to the following static checker warning: sound/soc/codecs/wcd938x.c:2092 wcd938x_tx_swr_ctrl() error: uninitialized symbol 'rate'. sound/soc/codecs/wcd938x.c 2064 switch (event) { 2065 case SND_SOC_DAPM_PRE_PMU: 2066 if (strnstr(w->name, "ADC", sizeof("ADC"))) { Use strncmp() here instead of strnstr(). The sizeof() will include the NUL terminator so it's size 4 and you wanted 3. The off by one means that strnstr() will do two memcmp()s. The equivalent of: if (memcmp(w->name, "ADC", 3) == 0) return w->name; if (memcmp(w->name + 1, "ADC", 3) == 0) return w->name + 1; return NULL; 2067 int i = 0, mode = 0; 2068 2069 if (test_bit(WCD_ADC1, &wcd938x->status_mask)) 2070 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC1]]; 2071 if (test_bit(WCD_ADC2, &wcd938x->status_mask)) 2072 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC2]]; 2073 if (test_bit(WCD_ADC3, &wcd938x->status_mask)) 2074 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC3]]; 2075 if (test_bit(WCD_ADC4, &wcd938x->status_mask)) 2076 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC4]]; 2077 2078 if (mode != 0) { 2079 for (i = 0; i < ADC_MODE_ULP2; i++) { 2080 if (mode & (1 << i)) { 2081 i++; 2082 break; 2083 } 2084 } 2085 } 2086 rate = wcd938x_get_clk_rate(i); 2087 wcd938x_set_swr_clk_rate(component, rate, bank); 2088 } 2089 2090 if (strnstr(w->name, "ADC", sizeof("ADC"))) 2091 /* Copy clk settings to active bank */ 2092 wcd938x_set_swr_clk_rate(component, rate, !bank); This a false positive, but you could silence it by combining it with the previous if block. 2093 break; 2094 case SND_SOC_DAPM_POST_PMD: 2095 if (strnstr(w->name, "ADC", sizeof("ADC"))) { 2096 rate = wcd938x_get_clk_rate(ADC_MODE_INVALID); 2097 wcd938x_set_swr_clk_rate(component, rate, !bank); 2098 wcd938x_set_swr_clk_rate(component, rate, bank); 2099 } 2100 break; 2101 } regards, dan carpenter
