misc: genwqe: card_utils: Whole a plethora of documentation issues
Including; demoting file header from kerneldoc to standard comment/ header, adding a variety of missing function argument documentation, repairing formatting (kerneldoc does not like blank lines) and the demotion of a kerneldoc header which shows no interest in providing documentation for any of its arguments. Fixes this the following W=1 issues: drivers/misc/genwqe/card_utils.c:37: warning: Incorrect use of kernel-doc format: * __genwqe_writeq() - Write 64-bit register drivers/misc/genwqe/card_utils.c:45: warning: Function parameter or member 'cd' not described in '__genwqe_writeq' drivers/misc/genwqe/card_utils.c:45: warning: Function parameter or member 'byte_offs' not described in '__genwqe_writeq' drivers/misc/genwqe/card_utils.c:45: warning: Function parameter or member 'val' not described in '__genwqe_writeq' drivers/misc/genwqe/card_utils.c:136: warning: Function parameter or member 'cd' not described in 'genwqe_read_app_id' drivers/misc/genwqe/card_utils.c:136: warning: Function parameter or member 'app_name' not described in 'genwqe_read_app_id' drivers/misc/genwqe/card_utils.c:136: warning: Function parameter or member 'len' not described in 'genwqe_read_app_id' drivers/misc/genwqe/card_utils.c:186: warning: bad line: drivers/misc/genwqe/card_utils.c:290: warning: Function parameter or member 'cd' not described in 'genwqe_alloc_sync_sgl' drivers/misc/genwqe/card_utils.c:290: warning: Function parameter or member 'sgl' not described in 'genwqe_alloc_sync_sgl' drivers/misc/genwqe/card_utils.c:290: warning: Function parameter or member 'user_addr' not described in 'genwqe_alloc_sync_sgl' drivers/misc/genwqe/card_utils.c:290: warning: Function parameter or member 'user_size' not described in 'genwqe_alloc_sync_sgl' drivers/misc/genwqe/card_utils.c:290: warning: Function parameter or member 'write' not described in 'genwqe_alloc_sync_sgl' drivers/misc/genwqe/card_utils.c:469: warning: Function parameter or member 'cd' not described in 'genwqe_free_sync_sgl' drivers/misc/genwqe/card_utils.c:469: warning: Function parameter or member 'sgl' not described in 'genwqe_free_sync_sgl' drivers/misc/genwqe/card_utils.c:716: warning: Function parameter or member 'count' not described in 'genwqe_set_interrupt_capability' drivers/misc/genwqe/card_utils.c:747: warning: Function parameter or member 'idx' not described in 'set_reg_idx' drivers/misc/genwqe/card_utils.c:747: warning: Excess function parameter 'index' description in 'set_reg_idx' drivers/misc/genwqe/card_utils.c:823: warning: Function parameter or member 'cd' not described in 'genwqe_ffdc_buff_size' drivers/misc/genwqe/card_utils.c:823: warning: Function parameter or member 'uid' not described in 'genwqe_ffdc_buff_size' drivers/misc/genwqe/card_utils.c:877: warning: Function parameter or member 'cd' not described in 'genwqe_ffdc_buff_read' drivers/misc/genwqe/card_utils.c:877: warning: Function parameter or member 'uid' not described in 'genwqe_ffdc_buff_read' drivers/misc/genwqe/card_utils.c:877: warning: Function parameter or member 'regs' not described in 'genwqe_ffdc_buff_read' drivers/misc/genwqe/card_utils.c:877: warning: Function parameter or member 'max_regs' not described in 'genwqe_ffdc_buff_read' drivers/misc/genwqe/card_utils.c:964: warning: Function parameter or member 'cd' not described in 'genwqe_write_vreg' drivers/misc/genwqe/card_utils.c:964: warning: Function parameter or member 'reg' not described in 'genwqe_write_vreg' drivers/misc/genwqe/card_utils.c:964: warning: Function parameter or member 'val' not described in 'genwqe_write_vreg' drivers/misc/genwqe/card_utils.c:964: warning: Function parameter or member 'func' not described in 'genwqe_write_vreg' drivers/misc/genwqe/card_utils.c:977: warning: Function parameter or member 'cd' not described in 'genwqe_read_vreg' drivers/misc/genwqe/card_utils.c:977: warning: Function parameter or member 'reg' not described in 'genwqe_read_vreg' drivers/misc/genwqe/card_utils.c:977: warning: Function parameter or member 'func' not described in 'genwqe_read_vreg' drivers/misc/genwqe/card_utils.c:995: warning: Function parameter or member 'cd' not described in 'genwqe_base_clock_frequency' drivers/misc/genwqe/card_utils.c:1012: warning: Function parameter or member 'cd' not described in 'genwqe_stop_traps' drivers/misc/genwqe/card_utils.c:1022: warning: Function parameter or member 'cd' not described in 'genwqe_start_traps' Cc: Michael Jung <mijung@gmx.net> Cc: Michael Ruettger <michael@ibmra.de> Cc: Frank Haverkamp <haver@linux.ibm.com> Cc: Joerg-Stephan Vogt <jsvogt@de.ibm.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Reviewed-by: Frank Haverkamp <haver@linux.ibm.com> # Please enter the commit message for your changes.
