If the iucv_register() functions fails, the error recovery calls iucv_unregister() which might cause the following stack backtrace: (<0000000000100ab2> show_trace+0xee/0x144) <00000000004f1842> panic+0xb6/0x248 <00000000001010a6> die+0x15a/0x16c <000000000011d936> do_no_context+0xa6/0xe4 <00000000004f84dc> do_protection_exception+0x2e8/0x3a4 <0000000000113afc> pgm_exit+0x0/0x14 <00000000004e786e> iucv_unregister+0x5a/0x17c (<00000000004e785e> iucv_unregister+0x4a/0x17c) <000000000076de74> hvc_iucv_init+0x228/0x5dc <00000000001000c2> do_one_initcall+0x3e/0x19c <00000000007524a2> kernel_init+0x28e/0x404 <0000000000105dd6> kernel_thread_starter+0x6/0xc <0000000000105dd0> kernel_thread_starter+0x0/0xc Remove the call to iucv_unregister() and remove the goto label as unregistering is the last step in the hvc_iucv initialization.

When the cmm module is compiled into the kernel it will crash when writing to the R/O data section. Reason is the lower to upper case conversion of the "sender" module parameter which ignored the fact that the pointer is preinitialized.

There is no difference if cpu_die is called from enabled or disabled context. Except that the fast_gup code might be called via cpu_die -> idle_task_exit -> __mm_drop -> crst_table_free. Which in turn grabs and releases a spinlock using the _bh ops, which is not allowed in irq disabled context, since spin_unlock_bh will unconditionally enable interrupts again. To get rid of the warning emitted by the softirq code just move the code to enabled context. In this case this doesn't fix a bug, we just get rid of a warning.

The usual way to recover a failed DASD ECKD request (cqr) is to create a new request with an appropriate recovery CCW program. Certain features, e.g. failfast, can be enabled per request and are stored in the requests flags. These flags have to be copied from the failed to the recovery request, to let the recovery request use the same features as the original one.

The functions the functions amd_ec_wait_write and amd_ec_wait_read have an unsigned return type, but return a negative constant to indicate an error condition. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust the return type of the functions amd_ec_write and amd_ec_read, which are the only functions that call amd_ec_wait_write and amd_ec_wait_read. amd_ec_write and amd_ec_read, in turn, are only called from within the function amd8111_access, which already returns a signed typed value. Each of the calls to amd_ec_write and amd_ec_read are updated using the following semantic patch: // <smpl> @@ @@ + status = amd_ec_write - amd_ec_write (...); + if (status) return status; @@ @@ + status = amd_ec_read - amd_ec_read (...); + if (status) return status; // </smpl> The patch also adds the declaration of the status variable.

drivers/i2c/algos/Kconfig makes all the algorithms dependent on !I2C_HELPER_AUTO, which triggers a Kconfig warning about broken dependencies when some driver selects one of the algorithms.
