Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (ufs, ibmvfc, megaraid_sas, lpfc, elx, mpi3mr, qedi, iscsi, storvsc, mpt3sas) with elx and mpi3mr being new drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "Updates for the interrupt subsystem: Core changes: - Cleanup and simplification of common code to invoke the low level interrupt flow handlers when this invocation requires irqdomain resolution. Add the necessary core infrastructure. - Provide a proper interface for modular PMU drivers to set the interrupt affinity. - Add a request flag which allows to exclude interrupts from spurious interrupt detection. Useful especially for IPI handlers which always return IRQ_HANDLED which turns the spurious interrupt detection into a pointless waste of CPU cycles.

However, struct SENSE_DATA is 18 bytes, with ccb->arcmsr_cdb.SenseData only being 15 bytes, resulting in a 3 byte over-read. Copy only the contents of ccb->arcmsr_cdb.SenseData and zero fill the remainder, avoiding potential over-reads.

2021-06-19scsi: elx: efct: Fix pointer error checking in debugfs initJames Smart1-6/+3
debugfs_create_xxx routines, which return pointers, are being checked for error by looking for NULL values. The routines may return pointer-munged -Exxx codes, so they should be using IS_ERR() to adapt. There are two cases: - The first case is on initial directory creation, which actually doesn't need to be checked. So remove the check. - Creation of the sessions subdirectory. Modify this creation to create under the initial directory created, and fix failure check.

efct_hw_iotype_is_originator() is returning a negative (-EIO) status which doesn't make sense for a u8 function type. Reviewing the code, the function only needs to return true/false, thus a bool status is most appropriate. Change the function return type and patch up the one callee as the bool inverses the if check.
