* drivers: misc: ad525x_dpot: Add missing check in dpot_read_spiDinghao Liu2021-03-101-0/+3
| | | | | | | | | | The use of dpot_read_r8d8() after checking dpot->uid is similar. However, we check the return value and return an error code only in one path, which is odd.

* misc: ad525x_dpot: Fix the enabling of the "otpXen" attributesDan Bogdan Nechita2016-03-021-1/+1
| | | | | | | | | | | Currently writing the attributes with "echo" will result in comparing: "enabled\n" with "enabled\0" and attribute is always set to false. Use the sysfs_streq() instead because it treats both NUL and new-line-then-NUL as equivalent string terminations.

| | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* drivers: misc: Mark functions as static in ad525x_dpot.cRashika Kheria2013-12-191-2/+2
| | | | | | | | | | | | | | | This patch marks the function ad_dpot_add_files() and ad_dpot_remove_files() as static in ad525x_dpot.c because they are not used outside this file.
