| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nct7904_data struct. SMI# interrupt for fan and voltage is Two-Times Interrupt Mode. Fan or voltage exceeds high limit or going below low limit, it will causes an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register. Thus, add the array fan_alarm and vsen_alarm to store the alarms for all of the fan and voltage sensors.

In the au1550nd driver we have 2 implementations of read_buf. The previously mentioned commit modified the au_read_buf() implementation to match the function pointer, but not au_read_buf16(). This results in a compiler warning for MIPS db1xxx_defconfig builds: drivers/mtd/nand/raw/au1550nd.c:443:57: warning: pointer type mismatch in conditional expression Fix this by updating the prototype of au_read_buf16() to take a struct nand_chip pointer as its first argument, as is expected after commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks"). Note that this shouldn't have caused any functional issues at runtime, since the offset of the struct mtd_info within struct nand_chip is 0 making mtd_to_nand() effectively a type-cast.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a binder transaction is initiated on a binder device coming from a binderfs instance, a pointer to the name of the binder device is stashed in the binder_transaction_log_entry's context_name member. Later on it is used to print the name in print_binder_transaction_log_entry(). By the time print_binder_transaction_log_entry() accesses context_name binderfs_evict_inode() might have already freed the associated memory thereby causing a UAF. Do the simple thing and prevent this by copying the name of the binder device instead of stashing a pointer to it.

This fixes issues we were seeing on various models, but it seems our old hardcoded 80ųA bias current was working around a firmware bug on at least one model laptop. In order to both have our cake and eat it, this commit adds a dmi based list of models where we need to override the firmware set bias current and adds the one model we now know needs this to it: The Lenovo Ideapad 100S (11 inch version).

There may be a race when two conversions complete at the same time on several ADCs. EOC can be read as 'set' for several ADCs, with: - an ADC configured to use IRQs. EOCIE bit is set. The handler is normally called in this case. - an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA request instead. It's then automatically cleared by DMA read. But the handler gets called due to status bit is temporarily set (IRQ triggered by the other ADC). So both EOC status bit in CSR and EOCIE control bit must be checked before invoking the interrupt handler (e.g. call ISR only for IRQ-enabled ADCs).

While I expected the "drain" flag at the stop operation would do processing the queued samples, it seems rather dropping the samples. As a quick fix, just drop the SNDRV_PCM_INFO_DRAIN_TRIGGER flag, so that the driver uses the normal PCM draining procedure. Also, put some caution comment to the function for future readers not to fall into the same pitfall.
