The config_log_add() function first calls config_log_put() with the variable 'cld' and then jumps to label 'out_cld', which will call the same function with the same 'cld' variable. However, at this point, 'cld' might have been already freed by the first invocation of config_log_put(). Even if we remove the invocation at that point, we will still get into trouble. This is because, in the error path, just below the label 'out_cld', we try to put 'params_cls' and 'sptlrpc_cld', which might also have been freed by config_log_put(). The point is that, config_llog_data::cld_sptlrpc and config_llog_data::cld_params members are assigned at the beginning of this function. To avoid this, do not call config_log_put() inside the else block, immediately jump to 'out_cld' instead. Moreover, remove assignments to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at the beginning, since we already assign them below in the function with 'cld_lock' held. As an additional benefit, code size gets smaller. before: text data bss dec hex filename 26188 2256 4208 32652 7f8c drivers/staging/lustre/lustre/mgc/mgc_request.o after: text data bss dec hex filename 26092 2256 4208 32556 7f2c drivers/staging/lustre/lustre/mgc/mgc_request.o Signed-off-by:

While in SNK_READY state, the explicit_contract seems to be set to true irrespective of whether an explicit contract was established for the current connection. TCPM also seems to report the pwr_opmode as TYPEC_PWR_MODE_PD always once the port gets into SNK_READY state. This isn't completely true as port gets into the SNK_READY state for non-pd type-c ports as well. This patch sets the explicit_contract flag only when the PS_READY message is received and the vbus has been detected by the port controller. Signed-off-by:

When an external USB synth is unplugged while the module is loaded, we get a null pointer deref. This is because the tty disappears while speakup tries to use to to communicate with the synth. This patch fixes it by checking tty for null before using it. Since tty can become null between the check and its usage, a mutex is introduced. tty usage is now surrounded by the mutex, as is the code in speakup_ldisc_close which sets the tty to null. The mutex also serialises calls to tty from speakup code. In case of tty being null, this sets synth->alive to zero and restarts ttys in case they were stopped by speakup. Signed-off-by:

platform_get_irq() returns an error code, but the dim2_hdm driver ignores it and always returns -ENODEV. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Also, notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure.

If the partner is not PD capable, we can not use a power role set request to swap roles. Use the data role set request instead. Also, if a partner is not PD capable, it does not really make sense to send a PD message to trigger a role swap. On top of that, we should really wait for the attempted role change to complete. Otherwise, it may well be that user space requests another role change immediately afterwards which will fail because the port is not yet in ready state. Trigger the role swap from data role change requests and introduce new state PORT_RESET and use it to solve the problem. This new state is mostly identical to ERROR_RECOVERY, only it does not cause a pending role change to fail. Use this new state also when initializing the driver. Rename ERROR_RECOVERY_WAIT_OFF to PORT_RESET_WAIT_OFF to better reflect its new meaning. Signed-off-by:

tcpm_default_state wasn't considering the port type when determining the default role. This change makes tcpm_default_state to consider port type as well. tcpm_default_state would return the following based on the port type: TYPEC_PORT_UFP - SNK_UNATTACHED TYPEC_PORT_DFP - SRC_UNATTACHED TYPEC_PORT_DRP - based on the preferred_role setting Signed-off-by:

While exiting ERROR_RECOVERY, choose default state based on the port type instead of current power role. Quoting from specification: 4.5.2.2.2 ErrorRecovery State This state appears in Figure 4-12, Figure 4-13, Figure 4-14, Figure 4-15, Figure 4-16 and Figure 4-17. The ErrorRecovery state is where the port removes the terminations from the CC1 and CC2 pins for tErrorRecovery followed by transitioning to the appropriate Unattached.SNK or Unattached.SRC state based on port type. This is the equivalent of forcing a detach event and looking for a new attach. Signed-off-by:

Role swap requests fail unless the current role is either SRC_READY or SNK_READY. This works fine for VCONN and data role swaps, where we immediately enter READY state after reporting a successful role swap to user space. However, on power role changes, the role swap is currently reported as successful while power negotiation is still in process. User space does not know this, and may request another role swap immediately after a power role swap is reported to be complete. This second role swap will fail with -EAGAIN. To fix the problem, report role swap completion after power negotiation is complete and the state machine enters SRC_READY or SNK_READY state. This is better anyway since it captures errors due to failed power negotiations. It also simplifies the code since the number of calls needed to report successful role swaps is reduced. Reported-by:
