Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley: "This series has a huge amount of churn because it pulls in Mauro's doc update changing all our txt files to rst ones. Excluding that, we have the usual driver updates (qla2xxx, ufs, lpfc, zfcp, ibmvfc, pm80xx, aacraid), a treewide update for scnprintf and some other minor updates. The major core change is Hannes moving functions out of the aacraid driver and into the core" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (223 commits) scsi: aic7xxx: aic97xx: Remove FreeBSD-specific code scsi: ufs: Do not rely on prefetched data scsi: dc395x: remove dc395x_bios_param scsi: libiscsi: Fix error count for active session scsi: hpsa: correct race condition in offload enabled scsi: message: fusion: Replace zero-length array with flexible-array member scsi: qedi: Add PCI shutdown handler support scsi: qedi: Add MFW error recovery process scsi: ufs: Enable block layer runtime PM for well-known logical units scsi: ufs-qcom: Override devfreq parameters scsi: ufshcd: Let vendor override devfreq parameters scsi: ufshcd: Update the set frequency to devfreq scsi: ufs: Resume ufs host before accessing ufs device scsi: ufs-mediatek: customize the delay for enabling host scsi: ufs: make HCE polling more compact to improve initialization latency scsi: ufs: allow custom delay prior to host enabling scsi: ufs-mediatek: use common delay function scsi: ufs: introduce common and flexible delay function scsi: ufs: use an enum for host capabilities scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc() ...

+ * @buf        : the buffer to place the translated FC Endpoint Security flag(s)
+ *               into
+ * @size       : the size of the buffer, including the trailing null space
+ * @fc_security: one or more FC Endpoint Security flags, or zero
+ * @fmt        : specifies whether a list or a single item is to be put into the
+ *               buffer
+ *
+ * The Fibre Channel (FC) Endpoint Security flags are translated into mnemonics.
+ * If the FC Endpoint Security flags are zero "none" is placed into the buffer.
+ *
+ * With ZFCP_FSF_PRINT_FMT_LIST the mnemonics are placed as a list separated by
+ * a comma followed by a space into the buffer. If one or more FC Endpoint
+ * Security flags cannot be translated into a mnemonic, as they are undefined
+ * in zfcp_fsf_fc_security_mnemonics, their bitwise ORed value in hexadecimal
+ * representation is placed into the buffer.
+ *
+ * With ZFCP_FSF_PRINT_FMT_SINGLEITEM only one single mnemonic is placed into
+ * the buffer. If the FC Endpoint Security flag cannot be translated, as it is
+ * undefined in zfcp_fsf_fc_security_mnemonics, its value in hexadecimal
+ * representation is placed into the buffer. If more than one FC Endpoint
+ * Security flag was specified, their value in hexadecimal representation is
+ * placed into the buffer. The macro ZFCP_FSF_MAX_FC_SECURITY_MNEMONIC_LENGTH
+ * can be used to define a buffer that is large enough to hold one mnemonic.
